(1) Calibration of Voltage
Conduct calibration in the case of voltage, current or thermocouple input. For thermocouple
input, calibrate reference junction compensation together.
Calibrate the voltage according to the instructions in Section “7.2.12 Data Calibration”
(Calibration of the voltage). (See pages 83-85.)
(2) Calibration of RTD (Resistance temperature detector)
Calibrate RTD according to the instructions in Section “7.2.12 Data Calibration” (Calibration of
the RTD). (See pages 83-85.)
[Note]
The dispersion of resistance for each wire must be 6 m or less.
Calibrate RTD at every channel.
Short-circuit the input terminals except the calibrating channel.
[Note]
(1) Calibrate at any one channel.
(2) When a shunt resistor is attached to the input terminal block for the current input, detach it
prior to calibration.
