Service operation modes
This section contains the description of the modes for the check of device efficiency
and calibration. As erroneous actions in this mode can lead to invalid measurement
results, only specially trained personnel should perform such operations.
11.1. Calibration conditions
Calibration of the device is not necessary in the current work. It is necessary only
after producing, repairing and also after checking with negative result.
To perform calibration the following means are necessary:
· Calibration plate with the deviation from flatness less then ±0,5 um for 250
mm length (or Flat block FDRF510.11.000, figure 4);
· Johansson gauge;
· reference wheel of the known diameter (or Reference wheel block
FDRF510.11.850, figure 5)
11.2. Get into operational modes
· To get into the operational modes it is necessary to turn-off the device (press
Red
button more then 3 seconds).
· Keeping
Green
button in pushed position turn-on the device (press
Red
but-
ton).
· Display shows “
CLbr.0
” message (the mode of calibration of the sensor's "
0
").
· To get into this mode it is necessary to press
Green
button (see. p. 11.3).
· For transition to next mode it is necessary to press
Blue
button.
· Display shows “
CLbr.b
” message (the mode of device base calibration).
· To get into this mode press
Green
button (see. p.11.4).
· To get out the mode of calibration press
Red
button.
11.3. Calibration of the sensor zero
· When zero calibration mode being enabled, the display shows the Johansson
gauge value used for calibration in increments of 0.5 µm.
· If editing of the Johansson gauge value is not required, go to the next step. To
edit the Johansson gauge value, press the
Blue
button, and the digit to be ed-
ited starts blinking. Changing over between the digits is made by pressing the
Blue
button while changing of values is made by pressing the
Green
button.
When editing is finished, press the Red button and confirm or cancel saving of
the parameter by pressing the
Green
button or
Red
button, respectively.
· Press the
Green
button, and the Johansson gauge value starts blinking,
which means that the device must be placed onto a flat plate and a Johans-
son gauge with nominal value of the previous step must be placed under the
measuring tip. The Johansson gauge must be tightly fitted to the flat plate and
supports and balls of the device must be firmly forced against the plate.
· Press the
Green
button, and the display shows current reading of the sensor
in its own coordinate system. By moving the device, assure that repeatability
of measurement results is obtained.
