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
flaws before measuring the diameter.
•
Prior to place the gauge is a need to clean the wheels and rails parts that con-
tact with gauge ball bearings and supports, of the mud.
•
At arranging the gauge, do not allow hitting its supports on the wheel and rail
•
It is necessary to inspect the gauge supports and laser sensors windows peri-
odically 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 gauge 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 sensor mounted in the gauge makes use of an c.w. 660 nm wavelength
semiconductor laser. Maximum output power is 1 mW. The sensor belong to the 2 laser
safety class. The following warning label is placed on the gauge body:
The following safety measures should be taken while operating the sensor:
•
Do not target laser beam to humans;
•
Do not disassemble the sensor;
Avoid staring into the laser beam
4.
General information
Electronic 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.
