5.4.10 Module Calibration

Calibration is to adjust the accuracy of ADAM module. There are several modes for module’s calibration: Zero calibration and span calibration. Only analog input and output modules can be calibrated. For example: ADAM 4011, 4011D, 4012, 4016, 4017, 4018, 4018M, 5013, 5017, 5017H, and 5018.

Zero Calibration

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

2.Make sure the module is correctly installed and properly config- ured for the input range you want to calibrate.

3.Use a precision voltage source to apply a calibration voltage to the +IN and -IN terminals of the ADAM-4011, 4011D, and 4012 modules. Use a precision voltage source to apply a calibration voltage to the Vin+ and Vin- terminals (or Iin+ and Iin-) of the ADAM-4014D and 4016 modules. Use a precision voltage source to apply a calibration voltage to the Vin0+ and Vin0- terminals for ADAM-4017, 4018, and 4018M modules.
