10. Working with the gauge
10.1. 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. In this case the short-term
work is possible after pressing any key.
10.2. Single measurement.
To perform measurement, it is necessary to:
•
turn the power on (press
Red
button). The display shows “
- - - - -
”;
•
place the gauge on the rails between the wheels;
•
make sure that the ball support is tight against the surface of the wheel and
side supports are adjacent to the flanges of the wheels;
•
press
Green
button.
•
in a 1 second the display will show the value of the 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:
10.3. 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 between the wheels
•
make sure the ball support is tight against the surface of the wheel and side
supports are adjacent to the flange of the wheels;
•
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)
•
reinstall the gauge 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.
10.4. 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.).
