Calibration • 95
6. Apply the correct span resistance to channel 0, detail resistance
value, see table 5-1.
7. Send “Span Calibration $(Addr)0” to analog input module five
times.
Repeat procedure 3 to procedure 7 two times.
Calibration Procedure for ND-6018 Firmware Rev B1.10
1. Disable all the channel and open detect function.
2. Select the correct input range, different input range have different
apply calibration voltage.
3. Apply the correct offset voltage to channel 0, detail voltage
value, see table 5-1.
4. Send “Offset Calibration $(Addr)1” to analog input module five
times.
5. Apply the correct span voltage to channel 0, detail voltage value,
see table 5-1.
6. Send “Span Calibration $(Addr)0” to analog input module five
times.
Repeat procedure 3 to procedure 6 two times.
Calibration Procedure for ND-6018 Firmware Rev E1.00 and
e1.00
1. Power off the module.
2. Connect the default pin to GND.(Because the calibration
procedures must be run under default mode).
3. Power on the module and use utility searching the module.
4. There must a “*” before the address ID.
5. Disable open detect function by sending command “$00O0”.
6. Only enable Ch0.
7. Select the correct input range. Different input range has to apply
different calibration voltage.
8. Apply the correct offset voltage to channel 0, detail voltage value,
see table 5-1.
9. Send “Offset Calibration $(Addr)1” to analog input module five
times.(Actually, the address now is “00”, so the command is
“$001”).
10. Apply the correct span voltage to channel 0, detail voltage value,
see table 5-1.
