1.8 Calibration

(Warning: Pls don't calibrate before you

really understand.)

Analog Input Calibration sequence:

Type code

Zero Input

0mV

0mA

Span Input

+15mV

+50mV

+100mV

+500mV

+1V

+2.5V

+20mA

1. Apply zero calibration voltage.
2. Warm up the module for at least 30 minutes.
3. Set the type code to the type you wish to calibrate.
4. Enable calibration.

-> Ref Sec.2.16

5. Perform zero calibration command.

-> Ref Sec.2.5

6. Apply span calibration voltage.
7. Perform span calibration command.

-> Ref Sec.2.4

8. Repeat steps 4 to 7 three times.

Excitation Voltage Calibration sequence:

1 Connect voltmeter to module’s excitation output pin.
2 Warm-Up for 30 minutes.
3 Output 0V.

-> Ref Sec.2.18

4 Trim the output until the value in voltmeter is closest to 0V.

-> Ref Sec.2.20

5 Perform Excitation Voltage Zero Calibration.

-> Ref Sec.2.21

6 Output 10V.

-> Ref Sec.2.18

7 Trim the output until the value in voltmeter is closest to 10V.

-> Ref Sec.2.20

8 Perform Excitation Voltage Span Calibration.

-> Ref Sec.2.22
