1.9 Calibration
Read Carefully Before Performing Calibration
Calibration Requirement for CB-7011/11D/11P/11PD/18/18P:
Notification:
1.
When calibrating a type 06, connect an external shunt resistor,
125 ohms, 0.1% (Ref Sec. 1.5).
2.
Connect calibration voltage (or current) signal to module’s in-
put. For CB-7018/18P, connect to channel 0. (For wire con-
nection reference, see Sec. 1.5)
3.
Before calibration, warm-up the module for about 30 minutes
to improve the accuracy.
Example Calibration Sequence for Type 00:
1.
Set Type to 00.
Refer to Sec. 2.1.
2.
Enable Calibration. Refer to Sec. 2.20.
3.
Apply Zero Calibration Voltage (0 mV)
4.
Perform Zero Calibration Command Refer to Sec. 2.6.
5.
Apply Span Calibration Voltage (15mV)
6.
Perform Span Calibration Command Refer to Sec. 2.5.
7.
Repeat step 1 to step 6 three times.
Calibration sequence for other type is similiar but different in step
1 to set different a type.
