Calibrating I/O

Calibrating Analog Channels

get prompted to verify channel calibration.

Click Yes to proceed with calibration. You are now prompted to apply 0 mA to the positive (+) and

negative (-) terminals. Once that is done, click

Yes to proceed.

You are now prompted to apply 20 mA to the positive (+) and negative (-) terminals. Once that is

done, click

Yes to proceed.

Once calibration is successfully completed, click OK to finish the process.

Resetting Calibration Data

You can reset the I/O channels calibrations to the factory calibrations in DeviceManager by selecting

Tools, I/O Channels, Reset Calibrate Data or in WebManager by selecting Administration, Reset,
