Wheel diameter measuring gauge, IDK
IDK [Revision 2.2] 4th September 2017

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 onto the wheel there is a need to clean the wheel
parts that contact with gauge ball bearings, side supports and measuring tip,
of the mud.

At arranging the gauge, do not allow hitting its supports on the wheel and any
measuring tip side hitting

At arranging the gauge, do not apply strong forcing in the direction of the
measuring tip movement. It can result in the gauge sag, that will bring about
the uncertain metering result

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 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. General information
Electronic gauge is designed for measuring wheel rolling circle diameter (amount
of wear) of railway, metro and tram in the course of checkup, examination, repair and
formation of wheel sets. Measurements are made directly on rolling stock without wheel
set roll-out.
