Analog I/O Modules Calibration

Analog input/output modules are calibrated when you receive them. However, calibration is sometimes required. No screwdriver is necessary because calibration is done in software with calibration parameters stored in the ADAM-5000 analog I/O module‘s onboard EEPROM.

The ADAM-5000 system comes with the ADAM utility software that supports calibration of analog input and analog output. Besides the calibration that is carried out through software, the modules incorporate automatic Zero Calibration and automatic Span Calibration at boot up or reset.

6.1Analog input module calibration

Modules: ADAM-5017, 5017H, 5018

1.Apply power to the ADAM-5000 system that the analog input module is plugged into and let it warm up for about 30 minutes

2.Assure that the module is correctly installed and is properly configured for the input range you want to calibrate. You can do this by using the ADAM utility software.

3.Use a precision voltage source to apply a span calibration voltage to the module‘s V0+ and V0- terminals. (See Tables 5-2 and 5-3 for reference voltages for each range.)

4.Execute the Zero Calibration command (also called the Offset Calibration command).
