Back-to-back distance measuring gauge, IMR-L
IMR-L [Revision 1.0] 1th October 2012

8. Operation principle
The method of back-to-back distance measurement is based on the derect
measurement the distance by laser triangulation sensor in-built onto the gauge.
9. Working with the gauge
9.1. Gauge turn-on
Press Red button to turn on the power. The display shows “ ErrP ” message if the ac-
cumulator battery voltage became lower then the control level.
9.2. Single measurement
To perform measurement, it is necessary to:
•
turn the power on (press Red button). The display shows “ - - - - - ”;
•
place the gauge on the inner surface of the wheel;
•
make sure that the magnetic support is tight against the surface of the wheel;
•
press Green button.
•
in a 1 second the display will show the value back-to-back distance.
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 back-to-back distance calculation contains an averaging al-
gorithm that allows eliminating the surface defects influence on the distance measuring
result. All the results of metering, performed after the
Red button pressing, are aver-
aged. 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;
•
make sure the magnetic support is tight against the inner surface 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 of the back-to-back distance;
•
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.).
