Measurement Technology HMS 990 USB Brochure

Reinforcement for Star Diagnosis compact 4 HMS 990 USB Measurement Technology is the ideal enhancement for the diagnosis capabilities of Star Diagnosis compact4. The combination of these two powerful devices allows service technicians to thoroughly check a vehicle in every detail. HMS 990 USB Measurement Technology can be used immediately on Star Diagnosis compact4 without any additional hardware installation. One great advantage is the direct link between the diagnosis applications Xentry Diagnostics (from model series 204) and DAS and the Measurement Technology software. If required, the universal oscilloscope can be called up directly from the diagnosis test procedure. Here, the measurement channel parameters are preset and a pass image is displayed. Extensive measuring options – The electrical system Service technicians can carry out a wide range of measurements on the vehicle’s electrical system. Various voltages, ignition and dwell angles – all the essential values can checked. The equipment can even be used to check whether all the alternator values are OK. The multimeter provides the opportunity to accurately check the basic electrical parameters such as voltage, current, resistance, frequency, temperature, and pressure. With this range of capabilities, the service technician always has a grip on that most sensitive vehicle component – the electrical system. Thorough examination The ignition rating must always be adjusted perfectly for the engine to give its best performance. HMS 990 USB Measurement Technology offers the service technician many means for checking the ignition ratings and to indicate variances. Service technicians can thus take the results of measurements as their basis for assessing whether the data displayed is OK, or whether it has to be corrected.

Are things running smoothly ? -- Analysis of individual cylinders Is the engine running as it should ? HMS 990 USB Measurement Technology makes it possible to check the duration of combustion by analyzing individual cylinders. Compression and rotational speed are also always in check. The service technician is immediately notified of deviations from the specified values.

Signal measurements with oscilloscopes Service technicians use the universal oscilloscope and the 12-channel oscilloscope to measure various signals such as those from the crankshaft position sensor or the camshaft Hall sensor. Recording can extend over several minutes. The service technician can store the measurements taken with the recorder function and retrieve them at a later point. HMS 990 USB Measurement Technology also offers numerous possibilities for the evalulation of the values measured.

New functionalities in the Measurement Technology

Software-Release 5.0.0

Overview

To meet the current requirements on vehicle diagnosis, additional functionalities have been added to the software for the HMS

990 USB measurement technology. These innovations enable the service personnel to an easier assessment of complex signals

and the technical hotline is given better possibilities to support and solve problems.

All the new functionalities will be explained to the user during the guided test. No special training is therefore necessary.

The software release 5.0.0 is available in the markets since Star Diagnosis Update 11/09.

New functionalities:

Signal measurement .......................................................................................................................................................................1 Storage of series of measurements................................................................................................................................................1 Storage of images...........................................................................................................................................................................2 Current clamps measuring range ...................................................................................................................................................2 Measurement of the start of delivery .............................................................................................................................................3

Signal measurement

With the new software release, amplitudes and

times can be measured directly including

automatic conversion to frequency. In addition,

all signals can be analyzed with a freely

selectable reference base (100%, 360°, 720°).

Storage of series of measurements

This functionality enables the service personnel

to save, archive and reload complete series of

measurements. This means that in the event of

an error, the technical hotline can assess the

situation more easily and provide better

support.
