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

8. Operation principle
The measurement of the diameter is performed according to the “three points”
technique, without the complete wheel coverage. The measurement method is based on
the diameter calculation by the known length of the segment chord (the distance be-
tween the ball bearings centers), which is obtained at placing the gauge onto the wheel.
The suggita of the segment is measured by means of the displacement converter. Video
presentation is placed here: https://youtu.be/pMienHfBizg
9. Working with the gauge and working in autono-
mous regime
9.1. Gauge turn-on
Press Red button to turn on the power. The display shows “ErrP” message if the
accumulator battery voltage became lower then the control level. In this case the short-
term work is possible after pressing any key.
9.2. Single measurement
To perform measurement, it is necessary to:
turn the power on (press Red button). The display shows “- - - - -”;
place the gauge onto the wheel;
make sure the ball supports are tight against the roll surface and side sup-
ports are adjacent to the edge of the wheel;
press Green button.
in a 1 second the display will show the value of the wheel diameter.
For viewing the result of measurement with indication discreteness of 0.01mm (it
is accessible only in a mode of direct indication) it is necessary to press Blue button,
thus displayed result will be shifted to the left on one digit. Next pressing Blue button will
lead to return of indication to a starting position:

9.3. Measurement with averaging
The program of the wheel diameter calculation contains an averaging algorithm
that allows eliminating the surface defects influence on the diameter measuring result.
All the results of metering, performed after the Red button pressing, are averaged. The
measurement is meant to be Green button pressing.
To carry out measurements it is necessary to
turn the power on (press Red button). The display shows “- - - - -”;
place the gauge onto the wheel
make sure the ball supports are tight against the roll surface and side sup-
ports are adjacent to the edge of the wheel;
press Green button;
display shows the value of pressing counter “n x”, where x–quantity of av-
eraged values;
in a 1 second display shows an average value over the set of metering (over
the quantity of Green button pressings)
move the gauge to a new position and repeat the measuring.
(The total quantity of measurements averaged in this way can run up to 9999.)
Press Red button to reset averaging result at switching to another wheel.
For viewing the result of measurement with indication discreteness 0.01mm (it is
accessible only in a mode of direct indication) it is necessary to press Blue button, thus
displayed result will be shifted to the left on one digit. Next pressing Blue button will lead
to return of indication to a starting position.
9.4. Gauge turn-out
The gauge turn-out occurs automatically. The display extinguishes if there were
no buttons pressings for 60 seconds, at that only blinking dot is shown. If there were no
button pressings for 4 more minutes, the gauge is turned out completely. You can turn
the gauge off by long pressing Red button (more then 3 sec.).
