Terminating the calibration mode
22. 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.
• 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.
