Outline

The Hand Held Particle Counter (HHPC-6) KR-12A is designed to detect particles fl oating in air, using the light-scattering method. The unit can display a particle count for six size ranges: ≥0.3 µm, ≥0.5 µm, ≥0.7 µm, ≥1.0 µm, ≥2.0 µm, and ≥5.0 µm. The sample air fl ow rate is automatically adjusted by the unit to 2.83 L / min. Temperature and humidity value of the sample air are also displayed. The unit can store the results of up to 500 measurements in an internal buffer and can show the data stored in the buffer. The built-in I / O port (serial interface) allows communication with a computer on which the supplied utility software or software that can use the RS-232-C protocol of the unit (such as the optional RP Monitor application) is installed. A serial printer (such as the optional Seiko Instruments DPU-414) can be used to print measurement data.The multi-point system interface allows connection of the unit to a multi-point system.The password-protected administrator setting is avail-able. This is suitable to prevent unauthorized users from making changes to measurement parameters and other settings. The unit operates on a rechargeable battery and is highly compact, allowing easy use in the fi eld. An AC adapter can also be used to power the unit.

Outline

Light source

This unit uses a laser diode as light source for the sen-sor. In comparison to other semiconductors, the life expectancy of laser diodes is somewhat shorter. When the laser diode nears the end of its service life, the light output falls below the rated level. There are considerable differences in service life between individual diodes. Some may fail already after several thousand opera-tion hours.

Preventing contamination of internal sensor

When the internal sensor has become contaminated, performance will decrease and servicing may become necessary. It is advisable to avoid measurement of air with containing mist, moisture droplets, very large particles, fi bers, or similar, or a very high amount of particles. Also take care to always store the unit with the inlet cover in place. After measurement of air with high particle number concentration, you should purge the unit using the supplied zero count fi lter. For details on purging, please refer to page 13.

3

Outline

Particle size detection

The unit is calibrated at the factory, using particles of known diameter and refractive index (polystyrene latex spheres). As the amount of scattered light by such particles is used as reference to determine the particle size, the measured size corresponds to the light-scattering size of polystyrene latex particles.

Periodic maintenance

In order to maintain continued measurement precision, it is recommended to have the unit checked and serviced once per year. Contact the supplier regarding periodic maintenance.

Measurement Modes

This unit has three measurement modes: Concentration, Totalize, and Audio.

Concentration In this mode, the particle count for each size chan-nel and the specified sample volume are used to display the particle number concentration (particles / L or particles / CF).

Totalize In this mode, the total particle count from the start of measurement for each size channel is displayed.

Audio In this mode, the total particle count from the start of measurement for each size channel is displayed. Each time the count reaches a multiple of a preset alarm level, a beep tone is sounded once.

41

Measurement

Measurement

Perform measurement as follows.

1. PreparationVerify that the isokinetic probe is mounted cor-rectly to the inlet of the unit (inlet cover is re-moved), or that the suction tube (with 1 / 8 inch hose barb) is connected.

Note

Perform measurement only when the isokinetic probe or suction tube with 1 / 8 inch hose barb is connected. Without these, correct measure-ment is not assured. The suction tube should be straight for a stretch of about 300 mm from the inlet.

Important

Do not operate the unit with the inlet and exhaust vent blocked, to prevent the risk of damage to the internal vacuum pump or electrical parts.

42

Measurement

2. SetupOn the setup menu, Setup Page 1, set the measure-ment mode with the “Cnt Mode” item. Make any other settings that are required.

4. StopWhen the preset sample volume is reached (or when F1 (STOP) is pressed while Sample Volume is set to MANUAL), the measurement stops. The measurement result data are stored in the buffer.

Note

When a measurement is completed, the light source and pump are turned off. When Sample Volume set to other than MANUAL, Number of Samples is set to 2 or higher, and when the Delay Time is set to 59 seconds or lower, the light source and pump are not turned off.

When the number of measurements exceeds the 500-data buffer capacity, older data will be sequentially overwritten by newer data (rotating principle).

5. Repeat When a setting other than MANUAL is selected for the Sample Volume, and Number of Samples is set to 2 or higher, or to INF (infi nite), preparations for the next measurement are made after the Delay Time interval has elapsed, and the next measure-ment starts. This operation is repeated for the number of times set with Number of Samples.

46

Measurement

Note

Use the stand to position the unit upright during measurement. If it is placed on its side, correct measurement is not assured.

While measurement is carried out with a Sample Volume setting other than MANUAL, pressing F1 (Stop) during the measurement will halt the measurement. In this case, measure-ment results are discarded.

CAUTION Do not operate the buttons of the unit while the unit is resting on the stand, to prevent accidents caused by tipping the unit over.

When operating the unit, always support it with your hand, so that no pressure is exerted on the stand.

RS-232-C Protocol

When communicating with external equipment such as a computer on which software using the RS-232-C protocol (such as RP Monitor) is installed, set the I / O port to Serial Type 2 (on Setup Page 2 of the setup menu).

Note

To ensure correct communication, the commu-nication parameters of the external equipment (computer) should be set as follows.

Baud rate: 4800 bpsData word length: 7 bitsStop bits: 2Parity: Even

Can not use “Sample Time” when the Serial Type 2 is selected for the I / O port (see page 26).

Important

Be sure to connect I / O port of the unit to serial interface of the computer. If computer has 9-pin D-sub connector (male type), use the supplied PC connector adaptor.

71

RS-232-C Protocol

Message Outline

MessageA character string exchanged between the KR-12A and the external equipment concluded by a terminator is called a “message”. Characters in messages use ASCII codes only. Except for the terminator, a message does not contain any control codes. The terminator consists of a <CR><LF> combination.

<CR>: Carriage return, character code (0DH)<LF>: Line feed, character code (0AH)

For example, the message “Q/D” actually consists of the following five characters: “Q”, “/”, “D”, <CR><LF>

Note

In this manual, the line terminator is expressed as <EOL>.

72

RS-232-C Protocol

The following two types of messages can be sent from external equipment to the KR-12A.

Command message: Message that controls opera-tion of the KR-12A.

Send request message: Message that requests infor-mation from the KR-12A.

The following two types of messages can be sent from the KR-12A to external equipment.

Response message: Message that confi rms that the KR-12A has received a message.

Information message: Message that contains mea-surement data or status in-formation.

73

RS-232-C Protocol

Message HeaderAll messages for the KR-12A start with a capital letter followed by a slash, such as “J/G0E0M2”. In this example, “J/” is the message header. The header serves to identify the message type.The following message headers are available:

X/, &X/ Command messageQ/, &Q/ Send request messageR/ Response messageF/ Function status messageJ/ Current status messageD/ Measurement data message&M/ Buffer range information message&P/ Delay time information message

74

RS-232-C Protocol

Message Send/Receive TimingWhen the KR-12A has received a correct send request message, it outputs the corresponding in-formation message. If it has received a command message or if there was an error in the received message, the KR-12A outputs a response mes-sage. In the mode for automatic measurement data transfer (S0), the KR-12A automatically outputs measurement data when a measurement is com-pleted.The external equipment can send a message to the KR-12A at any time. However, when sending sev-eral messages in sequence, it is necessary to wait until the information message or response mes-sage to the previous message has been received. Alternatively, it is possible to wait an appropriate time between messages (at least 1 second).In case of a sequence of messages where process-ing of the previous message must be completed first (such as “X/L1” followed by “X/G1”), it is necessary to check the KR-12A status before send-ing the second message.

75

RS-232-C Protocol

Processing Received Messages on External Equipment

Normally, the external equipment will be able to anticipate the kind of message that will be re-turned by the KR-12A in response to a given in-put. However, in the mode for automatic measure-ment data transfer (S0), the KR-12A automatically sends measurement data when a measurement is completed. If an external message is input at about the time of measurement completion, the decision which message will be output fi rst by the KR-12A depends on timing factors and cannot be reliably predicted. This must be taken into consideration when programming the external equipment.The external equipment can examine the header of a message received from the KR-12A to determine the type of message.

Buffer DataThe data in the buffer of the KR-12A are assigned an address in ascending order, from 0 to 499. When there are more than 500 data, the oldest data are sequentially replaced by new data. When-ever old data are replaced by new data, all address numbers are reassigned, so that later data always have higher address numbers. This must be taken into consideration when reading data by specify-ing the address.

76

RS-232-C Protocol

Command Messages

By sending command messages to the KR-12A, external equipment can control the operation of the KR-12A.A command message starts with the header “X/” or “&X/” followed by one or several commands, for ex-ample “X/C”, or “X/V1D3A0”.When the KR-12A receives a command message, it re-turns an appropriate response message. If all elements in a command message are valid commands, the response message is “R/ACK” (acknowledge). If the command message contains an invalid element, the message is ignored and the response message indicates the error type, such as for example “R/ER2”.The explanation in this section lists only the commands themselves. Remember that these must always be pre-ceded by the “X/” or “&X/” headers. For example, the initialize command shown on the next page is “C”, but the actual command message must be X/C<EOL>.

In the explanations below, a lower-case “n” is used for numerals. Thus, “Sn” can be “S0”, “S1”, etc. The meaning of each number is explained in the respective section.

77

RS-232-C Protocol

Messages start with the header “X/”

Initialize Command “C”The command “C” has the following effects:

- Light source and pump are turned off.- Measurement is terminated.- Messages prepared for sending to external

equipment (including any message that is currently being sent) are discarded.

Other items and measurement settings are not af-fected.

Important

If the command “C” is input while the KR-12A is sending a message to exter-nal equipment, the remaining part of the message is discarded, i.e. the received message will be truncated.Sending the command “C” should therefore be avoided in such situations, or proper steps should be taken to deal with the truncated message.

Example: X/C<EOL>

78

RS-232-C Protocol

Set Measurement Data Send Mode Command “Sn”

S0 At completion of measurement, measurement data are output automatically. This is called “S0 mode”.

S1 Measurement data are only output when a send request message “Q/D” is sent from the external equipment to the KR-12A. This is called “S1 mode”.

When the unit is turned on, the same settings as used before it was last turned off will be estab-lished.

Send Request Messages

By issuing a send request message, external equipment can request information from the KR-12A. When the KR-12A receives such a message, it outputs the cor-responding information message.A send request message starts with the header “Q/” or “&Q/” followed by a single character that indicates the kind of requested information. Differently from command messages, it is not possible to send several requests in a single send request message.

Messages start with the header “Q/”

Q/F<EOL> Get function status information This comprises measurement setting conditions etc. For an explanation of the function status mes-sage, see page 86.

Q/J<EOL>Get current status information This comprises information on the current opera-tion status of the KR-12A. For an explanation of current status messages, see page 88.

Q/D<EOL> Get measurement dataFor an explanation of measurement data messages, see page 89.

Example: Q/F<EOL>

85

RS-232-C Protocol

Messages start with the header “&Q/”

&Q/M<EOL>Get buffer rangeRequests information on range of stored buffer data.For an explanation of the buffer range information message, see page 91.

&Q/Dn1,n2<EOL>Get buffer dataRequests the sending of a range (n1 to n2) of stored buffer data. n1 and n2 are the buffer ad-dresses for the range boundary. When n1 is omit-ted, data are sent from the oldest data to n2. When n2 is omitted, only the n1 data are sent. This causes the KR-12A to send the measurement data report message “D/” for the specifi ed number of times.

&Q/P<EOL>Get delay time settingRequests information on the delay time setting of the KR-12A.For an explanation of the delay time information message, see page 91.

Example: &Q/D0,5<EOL>&Q/P<EOL>

Current Status MessageThe current status message indicates the current operation status of the KR-12A. The message is output in response to the current status request command “Q/J”.

The format of the message is as follows:J/GnEnMn<EOL>The meaning of the letters is described below.

Gn indicates whether measurement is possible or not.

G0 Measurement is possible.G1 Measurement is not possible (light source

is off, or error has occurred).

En indicates whether an error has occurred.E0 No error has occurred.E1 Error has occurred.

Mn indicates whether measurement is currently being carried out.

M0 Measurement is not being carried out.Light source and pump are off.

M1 Measurement is not being carried out.Light source and pump are on.

M2 Measurement is being carried out.

Example: J/G0E0M2<EOL>

89

RS-232-C Protocol

Measurement Data MessageThe measurement data message contains the mea-surement result for the immediately preceding measurement. The timing when this message is sent depends on the measurement data send mode (S0 or S1).

S0 mode When a measurement is completed, the data are automatically sent to the external equip-ment, provided that data transfer is possible at that point. If the clear to send (CS) input is OFF, data are not sent.

S1 modeMeasurement data are sent to the external equipment when the KR-12A receives the mea-surement data request command “Q/D”.

If there is a measurement data request while no measurement data are available, only the follow-ing message is returned: D/<EOL>When measurement data are sent, the message format is as shown on next page.

90

RS-232-C Protocol

The label name is a variable-length string of up to 10 characters (see page 57). The time is expressed in 24-hour format.The count for each particle size and the tempera-ture and humidity information are expressed as 9-digit numbers.The fi rst numeral of the particle count has the fol-lowing meaning:

“0” Measurement was carried out normally.“1” Over-range has occurred (particle count has

exceeded eight digits).

Buffer Range Information MessageThe buffer range information message provides information about the range of saved buffer data. It is sent in response to the get buffer range mes-sage “&Q/M” sent by the external equipment.The format of the message is as follows:

&M/n1,n2<EOL>n1 and n2 indicate the lower and upper end of the buffer.If no data are stored in the buffer, only the mes-sage “&M/1,0” is returned.

Example: &M/0,120<EOL>(This indicates that 121 data from 0 to 120 are stored.)

Delay Time Information MessageThe delay time information message provides information about the delay time setting of the KR-12A. It is sent in response to the get delay time message “&Q/P” sent by the external equipment.

Example: &P/01:00:00<EOL>

92

RS-232-C Protocol

Response Messages

When the KR-12A receives a message other than a send request message from external equipment, it returns a response message. If the received message can be processed normally, the response message is “R/ACK”. If there is a problem, one of three error messages is returned (“R/ER1” through “R/ER3”). The messages have the following meaning.

R/ACK<EOL>Command was received normally.

R/ER1<EOL>A data transfer error was detected.

R/ER2<EOL>The message contains an invalid element.

R/ER3<EOL>The command cannot be carried out.

If the external equipment issued a send request com-mand such as “Q/F”, the KR-12A returns the requested information instead of a response message.The message “R/ER3” can be due to the following reasons:

- Measurement start was attempted while the KR-12A is not in a condition where measure-ment can be carried out.

- Measurement stop was attempted while the KR-12A is not in manual mode.

93

RS-232-C Protocol

If a command message with more than one command is sent, the KR-12A waits until the last command is re-ceived, and then returns one response message only. If there is an error anywhere in the command message, the response message will be an error message. Otherwise, the acknowledge message will be sent.

Application Example

For reference, a message exchange between the KR-12A and external equipment is shown next page. In this example, the KR-12A is set to manual mode, and the measurement is carried out under control of the external equipment for a certain amount of time.When programming external equipment, you should allow for some fl exibility, in order to ensure reliable operation. In particular, you should provide restore routines that enable the program to deal with instances when the KR-12A does not respond or does not return the expected string.

Troubleshooting

Spurious Counts

Use the supplied zero count fi lter and purge the unit. If even after repeated purging the unit still registers spuri-ous counts, that is if the reading of 1 or less in 5 minutes (0.3 µm range), or 1 or less for 14 L (0.3 µm range) is not achieved, check whether the zero count fi lter was mounted correctly. If the fi lter was mounted correctly, the cause may be internal contamination or a leak. Please contact your supplier to have the unit checked.

“CAL Alarm” Indication Is Shown

Use the supplied zero count fi lter to purge the unit. If the “CAL Alarm” indication does not disappear after repeatedly purging the unit, the cause may be internal contamination or a defect in the optical system. Please contact your supplier to have the unit checked.

Note

For details on purging the unit, please refer to page 13.
