The following example uses 5 inch (interval) measurement standards and an
Accurate Technology ProTable as the measuring system under calibration.
Other applications would use a similar procedure.
1. Set
Pr39
(Compensation Enable) to 1 .
2. Set
Pr40
(Compensation Interval) to the length of the measurement
standards multiple that will be used during the calibration, in this
example
5.000 inches.
3. Exit Programming Menu.
4.
Turn off the readout with the On/Off button. Press and Hold
the
DATUM
key and the
ON
/
OFF
key for approximately 10 seconds. After
that time, the LCD will turn on and complete a segment test. You
can release the
ON
/
OFF
and
DATUM
keys at this time.
5. After the LCD test is complete, the Readout will show the firmware
version for about 1 second. This will be followed by the LCD
showing the current position alternating with
cal . This indicates
the Readout is in the correction table calibration mode. This
alternating display will continue throughout the calibration process.
6. Place the measuring system moving jaw (stop) against the fixed
jaw (stop). Press
DATUM
to zero the Readout.
7. Press the
F1
key. This enters the first correction point into the
table. The LCD will momentarily show Co 0 indicating that the
entry was accepted.
8. Open the jaw and place the first measurement standard (5.000in.)
against the back-fence. Close the moving jaw until the face of the
jaw gently touches the measurement standard. Press the
F1
key.
The LCD will show Co 1 indicating the first measurement point
has been digitized.
9. Open the jaws and insert another measurement standard
(10.000in). Close the moving jaw until the face of the jaw gently
touches the measurement standard. Press
F1
. The LCD will show
Co 2 briefly. Continue this step with additional standards placed
end to end every 5.000
” until the maximum measuring range has
been achieved.
10. After the last correction point has been digitized, press the
F2
key.
The LCD will momentarily show
CoE
indicating that the calibration
process has ended.
