1.9 Calibration

Don’t Perform Calibrate Until You Really Understand.

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.
