Calibrating I/O
Calibrating RTD
When calibrating the IOLAN Analog input for RTD, you will need a resistor that is better than .05%
Ohms accuracy. When you calibrate one channel, all RTD channels are automatically calibrated for
that range; if another channel is set for a different range, you will need to calibrate that channel
separately, but all channels that use that range are automatically calibrated.
Calibrating Analog Channels
Analog Input can be calibrated for Analog and Temperature IOLAN models.
Select the channel you want to calibrate. This example uses an A4 model that has channel A1 set to
Current with a Range of 0 to 20mA.
If you have not disabled confirmation messages (Tools, Options in DeviceManager only), you will
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.
