Calibration Requirement for I-7011/11D/11P/11PD/18/18P
Notification :
1 While calibrate type 06, need connect external shunt resistor,
125 ohms, 0.1% (Ref Sec.1.5).
2 Connect calibration voltage(or current) signal to module’s
input. For I-7018/18P, connect to channel 0. (Wire connect ref
Sec.1.5)
3 Before calibration, warm-up module about 30 minutes for bet-
ter accuracy.
Example Calibration Sequence for Type 00 :
1 Setting Type to 00 -> Ref Sec.2.1.
2 Enable Calibration -> Ref Sec.2.20.
3 Apply
Zero Calibration Voltage (0mV)
4 Preform Zero Calibration Command -> Ref Sec.2.6.
5 Apply Span Calibration Voltage (15mV)
6 Perform Span Calibration Command -> Ref Sec.2.5.
7 Repeat step1 to step6 three times.
Calibration sequence for other type is similiar but different in step
1 to set different type.
