8.4 Analog Output Calibration

Model: ADAM-4021/4024

The output current of analog output modules can be calibrated by using a low and high calibrating value. The analog output modules can be configured in one of the two ranges, 0-20 mA and 4-20 mA. Since the low limit of the 0 - 20 mA ranges, 0 mA, is an absolute reference (no power, or immeasurably small power). However, just two levels, 4 mA and 20 mA, are needed for calibration.

1.Apply power to the analog output module and let it warm up for about 30 minutes.

2.Assure that the module is correctly installed, and its configuration is according to your specifications. It should match the output range that you want to calibrate. You can do this by using the ADAM utility software. (Please refer to Appendix D, Utility Software.)

3.Connect either a 5-digit millimeter or voltmeter with a shunt resistor (250Ω, 0.01% , and 10ppm) to the screw terminals of the module
