1.
Safety precautions and measurement conditions
•
The metering accuracy depends greatly on the wheel surface quality. There-
fore it is necessary to carry out the check and presorting of the wheel surface
roughness and flaws before measuring the diameter.
•
Prior to place the gauge is a need to clean the wheels parts that contact with
gauge and the place of laser beam hit.
•
At arranging the gauge, do not allow hitting its supports on the wheel
•
It is necessary to inspect the gauge supports periodically and to cleanse them
•
To save the battery power the display extinguishes if there were no buttons
pressings for 60 seconds, at that only blinking dot is shown. Pressing any but-
ton just turns on the display and does not act in any other way in this case.
2.
Electromagnetic compatibility
The back-to-back distance measuring gauge (IMR Series) has been developed
for use in industry and meets the requirements of the following standards:
•
EN 55022:2006 Information Technology Equipment. Radio disturbance char-
acteristics. Limits and methods of measurement.
•
EN 61000-6-2:2005 Electromagnetic compatibility (EMC). Generic standards.
Immunity for industrial environments.
•
EN 61326-1:2006 Electrical Equipment for Measurement, Control, and Labor-
atory Use. EMC Requirements. General requirements.
3.
Laser safety
The device make use of an c.w. 660 nm wavelength semiconductor laser. Maxi-
mum output power is 1 mW. According to IEC 60825-1:2007 the device belong to the 2
laser safety class. The following warning label is placed on the laser body:
The following safety measures should be taken while operating the IMR:
•
Do not target laser beam to humans;
•
Do not disassemble the laser scanning module;
•
Avoid staring into the laser beam.
4.
General information
Gauge is designed for measuring back-to-back distance of railway, metro and
tram wheels in the course of checkup, examination, repair and formation of wheel sets.
Measurements are made directly on rolling stock without wheel set roll-out.
