SERIES 8159 SIGNAL CONDITIONER MANUAL

8.
With no load on the transducer, verify the instrument reading is low.
9.
Depress the INCREMENT (S2) switch and hold until the TARE LED illuminates. The
readout should be ZERO +/- 1 digit.
10.
Apply the FULL SCALE load to the transducer. If a strain gage simulator is used, set it
to the desired mV/V setting. The instrument should display a value greater than 01000.
For optimum performance the readout should be closer to 19000. Ignore decimal point.
11.
Depress the DECREMENT (S3) switch and hold until the CAL LED illuminates. The
readout should display the CAL /- 1 digit.
The CALIBRATION sequence is now complete.
NOTE: Calibration information (tare and slope values) is maintained in non- volatile
memory and is updated every time CALIBRATION Steps 9 and 11 are performed. TARING
the display does not change the scale factor (slope value) calculated when Step 11 is
completed.
RCAL (SIMULATED) LOAD METHOD
1.
Connect the strain gage transducer to the instrument using Figure 4 as a reference. Do
not apply any load to the transducer.
2.
An RCAL resistor is provided and installed on the rear panel printed circuit board.
3.
Apply power to the instrument.

NOTE: If the instrument was previously calibrated and no new calibration is required, do
not proceed any further. All previous calibration information is stored in non-volatile
EEPROM and is ready for use when power to the instrument is reapplied.
