5.1 How to Calibrate the Analog Input Modules ?
What do you need to do calibration ?
1. One 5 1/2 digit multimeter.
2. A voltage calibrator or very stable and noise free DC voltage
generator.
3. A precision resistance decade box or discrete resistors.
4. NuDAM Administration Utility.
Calibration Procedure for ND-6011/D, 6012/D,6014D, 6017
1. Select the correct input range, different input range have different
apply calibration voltage.
2. Apply the correct offset voltage to the analog input module, detail
voltage value, see table 5-1.
3. Send “Offset Calibration $(Addr)1” to analog input module five
times.
4. Apply the correct span voltage to the analog input module, detail
voltage value, see table 5-1.
5. Send “Span Calibration $(Addr)0” to analog input module five
times.
6. Repeat procedure 2 to procedure 5 two times.
