Channel: Select the Analog Input or Analog Output Channel from the list to calibrate.
Sensor: Select the input type and its range to be calibrated.
Note:
It is always advisable to do the calibration of 3
rd
Channel on the card for more accurate
calibration.
Type: Select the AO type to be calibrated as Voltage or Current.
Note: The AO Card Dip switch also need to be set as per the type selection.
Calibration Password: Set Password to access the Calibration parameters.
Note
Channel #3 should be calibrated first in all types of Analog Input cards. An analog temperature
sensor is installed in channel # 3. When channel # 3 is calibrating, the cold junction voltage measured by
this temperature sensor will be loaded into a register. If channel # 3 is not calibrated, the default value of
cold junction voltage will be used for all channels. It does not matter what order you perform calibration after
calibrating input 3, there is no need to follow a sequence, and any one of T/C, RTD, mA or VDC can be
done independently.
