CALIBRATION INSTRUCTIONS (CONT)
9. Enable the CAL switch. Reference
PROGRAM INSTRUCTIONS
Step 1
on Page 10 to enable the CAL switch.
Note:
Enabling the CAL switch allows only one attempt at calibrating
the instrument. If calibration is not successful, repeat the whole
calibration procedure.
10. Apply no load to the transducer.
11. Depress the TARE (S2) switch once. The TARE LED should illuminate
and the readout should be ZERO +1 digit.
12. Apply the FULL SCALE load to the transducer. If a voltage generator is
used, set it to the the desired voltage setting. The instrument should
display a value greater than
01000
. For optimum performance the
readout should be closer to
32000.
Ignore the decimal point.
13. Depress the CAL (S3) switch once. The CAL LED should turn on and the
readout will display the CAL 1 digit.
14. The CALIBRATION sequence is now complete.
NOTE:
Calibration information (tare and slope values) are maintained in
non-volatile memory and are updated each time the CAL switch is
depressed. TARING the display stores the new tare value, but does
not change the scale factor (slope value).
