5. Click Calibration Command, and select Begin Calibration.
6. Click the Download to Device button.
The status indicator of a channel in calibration mode flashes green. The
status indicator of a channel not in calibration turns off.
7. Apply 0.00 mV to the input, referring to the wiring diagram in this
section.
8. Click Accept Low Input.
9. Click the Download to Device button.
The status indicator(s) for the channel(s) being calibrated blink(s) green.
IMPORTANT
Calibration in millivolts allows the sensor calibration to be
independent of CJC. The cold junction compensation is not
active for the mV input regardless of the CJC setting. The
module must have the exact voltage at its input terminals.
Thermocouple wire or a voltage source that simulates a TC
voltage should not be used.
Select Accept Low Input and
