Cleaning and Inspecting Techniques This section contains instructions for periodic cleaning and inspection of the instrument as preventative maintenance

measures. It also contains specific cleaning procedures to be conducted after disassembly. Parts having identical

cleaning procedures are grouped under common headings. No special tools are required.

Interior Cleaning

WARNING

Ventilate work area thoroughly when using solvents. Observe manufacturers warnings on

solvent containers with regard to personnel safety and emergency first aid. Be sure that first

aid equipment is available before using chemicals. Observe all shop safety and fire

precautions.

Magnetic Cleaning

CAUTION

Do not use solvents to clean transformers or inductors. The chemical action of solvents may

remove the varnish from the wire coils, rendering the components useless. The solvent also

neutralizes the adhesive of the cover tape, resulting in eventual tape separation from the

windings.

Clean transformers and inductors with a dry, non-metallic, soft bristle brush.

Printed Circuit Board Cleaning The printed circuit board assemblies in the ELI 250/210 system contain static sensitive devices. Use special

handling procedures to prevent damage due to ESD.

Clean assembled parts with a vacuum cleaner or low pressure compressed air (30 psi). Take care when cleaning

printed circuit boards that wires or component leads are not bent back and forth in such a manner as to weaken them

and cause them to eventually break.

Dry with low pressure compressed air.

____________________________________________________________________________Section 2

2-3

Metallic and Plastic Parts Cleaning

CAUTION

Do not wipe over surfaces of nameplates or labels with abrasive cleaners or materials,

as this will eventually wear away the nameplate information. Do not use solvents to

clean plastic parts.

Brush all surfaces and parts with a nonmetallic, soft bristle brush.

Wipe metal surfaces with soft, nonabrasive cloth dampened with isopropyl alcohol.

Dry surfaces with clean cloth.

Wipe surfaces of nameplates and labels with dry cloth.

Exterior Cleaning Use a damp cloth to clean external covers and the line cord. Do not use alcohol, solvents, or cleaning solutions.

These cleaning agents may damage the surfaces of the instrument.

setting is ignored if an active ECG signal is detected, during transmission, or while rhythm printing.

ELI 250/210__________________________________________________________________________

3-10


Flash Size Flash Size indicates the ECG storage capacity of your electrocardiograph. Normal Flash Size is the standard

memory capacity. If the optional expanded memory has been installed, Expanded will be displayed.

ID Format

This option defines the format for the patient ID information prompts. There are three standard formats: short,

standard, or long. A custom ID format is optional when downloaded from the E-Scribe Data Management System.

The short format includes the patient's last name and first name, patient ID number, date of birth, which will

automatically calculate the age, and gender field.

The standard format includes the patient's last name, patient ID number, age, height, weight, gender, race,

medication 1, medication 2, and a location field.

The long format is identical to the standard format except that it includes the patient's first name, room and comment

fields.

The custom format, which is designed in the Mortara E-Scribe Data Management System, can be downloaded to the

ELI 250. The custom ID format is uniquely designed to meet your facility’s needs. Please see Appendix A to

download a Custom ID.

AC Filter

The ELI 250 removes 60Hz or 50Hz interference. The setting you select depends on the line frequency in your

country. Always use the 60Hz setting in the United States. If the AC interference is present, check to see that the

proper AC filter is selected.

Paper Speed

The writer speed can be configured at 25mm/s or 50mm/s for default ECG printouts. For rhythm printouts and

display, speeds of 5mm/s or 10mm/s are also available. See Section 4 to change speeds for display or rhythm

printing.

____________________________________________________________________________Section 3

3-11

Filter The ECG plot frequency filter (or print filter) can be set to 40Hz, 150Hz, or 300Hz. The plot frequency filter does

not filter the acquired digital record. A 40Hz plot filter setting will reduce the noise (40Hz and higher frequencies)

on the printed ECG, a 150Hz plot filter setting will reduce the noise (150Hz and higher frequencies) on the printout

and a 300Hz plot filter setting will not filter the printed ECG.

Height/Weight Units

This option defines the units of weight and height to either pounds/inches (lb/in) or kilograms/centimeters (kg/cm).

Date Format This option defines the format for entering and displaying the patient’s date of birth in either the U.S. format or the

European format.

For example: July 16th

, 2003 is displayed as follows: US Date Format: MM/DD/YYYY (07/16/2003) European Date Format: DD.MM.YYYY (16.07.2003)

NOTE: the date format option does not modify the acquisition date printed on each ECG. Using the

example above, the acquisition date would print as 16-Jul-2003.

Plot Format This option defines the default for one of five available plot formats in either Standard or Cabrera presentation.

Please note that regardless of the plot format selected, 10 seconds of 12-leads are always stored.

The ECG plot options are:

Format Option

ECG Data

3+1

2.5 seconds of 12 leads in a three-channel format and the fourth channel is a 10 second rhythm strip of lead II (user defined).

6

5 seconds of 12-leads in a six-channel format

3+3

2.5 seconds of 12 leads in a three-channel format plus 10 second rhythm strip of leads II, V1 and V5 (user defined) in a three-channel format.

12

10 seconds of 12 leads in a 12 channel format

6+6

10 seconds of 12 leads in a 2 page printout (six channels per page)

Interpretation Option

ELI 250/210__________________________________________________________________________

3-12

The ELI 250 automatically analyzes ECGs and prints the optional interpretation on the ECG printout. This option

allows you to select or suppress the “interpretive” text on the ECG report.

NOTE: A qualified physician should review the computer generated ECG interpretation before the

treatment of any patient.

Reasons

The reason statements indicate why a particular interpretive statement was printed. Reason statements print in

[square brackets] within the interpretive text (if the interpretation is turned on). Turning the reason statement

function on or off does not affect the measurements performed or the interpretive statements selected by the analysis

program.

For Example:

Anteroseptal Infarct [40+ MS Q WAVE IN V1-V4]

Where “Anteroseptal Infarct” is the interpretive statement.

And “40+ MS Q WAVE IN V1-V4” is the reason statement or explanation as to why the

interpretive statement was printed.


Append

A status or statement phrase can be appended to the ECG and printed under the interpretive text printout. Either

“unconfirmed report” or “reviewed by” can be selected. However, if you wish to have nothing appended to the

ECG, “blank” may be selected.

Number of Copies

This option defines the number of printed copies when an ECG is taken. A zero (0) setting prints the original only;

one (1) prints the original plus 1 copy; two (2) prints the original plus 2 copies, and so on. Up to 9 copies may be

selected.

ECGs Retrieved

____________________________________________________________________________Section 3

3-13

This option defines the number of ECGs retrieved from an E-Scribe data management system. The ECGs are

retrieved by ID number. A zero (0) setting retrieves the most current ECG for that ID number. Settings from one

(1) to nine (9) retrieve the most current ECG plus “X” number of ECGs identified by the entered value.

EXAMPLE: If you enter the number 5, you will retrieve the most current ECG plus the five preceding ECGs for

that ID number. ECGs retrieved from the E-Scribe are only printed at the ELI250 and not saved.

Delete Rule

This option defines the ECG auto delete status in the patient directory. ECGs that are marked for deletion will be

automatically removed or erased based on their record size to make room necessary for the new ECG record. ECGs

are only erased from the directory when they are marked for deletion and if the directory becomes full. The delete

rule selections are:

Post Plot = ECG is automatically marked deleted after printing.

Post Transmit = ECG is automatically marked deleted after transmission.

Post Plot/Transmit = ECG is automatically marked deleted after transmission and printing.

Storage Sensitivity The ECG storage sensitivity setting dictates the resolution of the stored record. The sensitivity settings are either

Normal or High. If the configuration value is set to High, the stored ECG will have a high resolution. As a result,

the records size will be large and will reduce the storage capacity in the ECG directory.

Auto Save ECG

This option defines whether or not the ELI 250 is to automatically save newly acquired ECGs in the directory, once

they are acquired and printed. If the auto save configuration option is set to NO, and the record is printed, the ELI

250 will prompt you to “Save ECG?” SAVE (F1) will store the ECG in the directory.

NOTE: manually save ECGs by selecting More (F5) from the Acquired ECG view and Save (F5).

Auto Print ECG

This option defines whether or not the ELI 250 will automatically print the ECG after acquisition. If the selected

configuration option is set to NO, a manual printout is possible after acquisition.

Baud Rate

The user-selectable baud rate determines the serial port’s data transmission rate in bits per second (bps). Set the

baud rate to: 9600, 19200, 38400, 57600, or 115200 bps for direct data transmission between the ELI 250 and

another Mortara cardiograph, and 38400 bps for a direct connection to the E-SCRIBE data management system.

Use A4 Paper

The ELI 250 accommodates use of Z-fold thermal paper in either the letter size (8.5 x 11 inches; 216 x 279 mm) or

the “A4” size (8.27 x 11.69 inches; 210 x 297 mm). The provided paper tray spacer is required for use with A4 size

paper. Enable this configuration option for A4 printing. The paper tray spacer should not be inserted if the letter

size paper is used.

Caps Lock All character entry is translated to upper case.
