13.5 Calibration

Completing the selected module calibration with the END mode

20.With

, select the END mode.

ADJUST MODE=END

>S_UNIT0 : MODULE No=0

DISPLAY CAL/EXEC END

21.PRESS the ENTER key.
22.With

, select STORE or ABORT.

A/D ADJUST END=ABORT

>S_UNIT0 : MODULE No=0

ABORT STORE

23.Press the ENTER key. Return to operation 2.

Terminating the calibration mode

24.When you return to normal measurement after completing calibration, turn off the power and

then back on.

CAL/EXEC mode (for calibration of a specified range)
• Items for calibration range

• Items for the calibration range vary depending on the type of module to be calibrated.
• For use with universal input modules, select the items for the calibration range from among

the following:
20 mV/60 mV/200 mV/2 V/6 V/20 V/50 V/Pt: 1 mA/Pt: 2 mA/Pt: 1 mA-H/Pt: 2 mA-H/Cu:
2 mA

• When the DC V/TC/DI input module is selected, RTD in the universal input module is not

displayed.

• The choice is 20 mA only for mA-input modules.
• For strain input modules, select from 2k, 20k, 200k and INIT.

INIT: Set defaults in the A/D Adjustment section. Calibration is necessary, however, after
execution.

• For digital input modules, select from 60mV and 6V.

• Displaying error messages

The following error messages are displayed.

• Attempted to remove the module during calibration. Or, hardware error: ERROR145
• Invalid calibrated data: ERROR144

Note

• When calibrating a high-precision RTD (Pt: [ ]-H), do so after calibrating the voltages to maintain

accuracy.

• When a calibrated data error appears, the error data are stored in memory.

• If ERROR145 appears, turn off the power and then back on to restart operation. If the same error occurs

again, the recorder may be defective.

• If ERROR144 appears, check the electrical connections and input data. If the same error occurs again,

the module to be calibrated may be defective.

• When calibrating a strain input module, first calibrate zero (ZERO) and then the span (SPAN).
