Pressure Calibrator

Calibration Adjustment

13

Adjust Voltage Input

To adjust the voltage input:

1.

Use the test lead set to attach the voltage output of the Calibrator to the
input of the Product.

2.

Send this command to put the Product into Voltage mode:

FUNC LOWER,DCV

3.

Use the Calibrator to input 0 V.

4.

When the reading is stable, send this command:

CAL_POINT[0] [0]

5.

Use the Calibrator to input 30 V.

6.

When the reading is stable, send this command:

CAL_POINT[0][1]

7.

The voltage range is now calibrated.

Adjust mA Input

To adjust the mA input:

1. Use the test lead set to attach the voltage output of the Calibrator to the input

of the Product.

2. Send this command to put the Product in Current mode:

FUNC LOWER,DCI

3. Use the Calibrator to input 0 mA.

4. When the reading is stable, send this command:

CAL_POINT[0][0]

5. Use the Calibrator to input 24 mA.

6. When the reading is stable, send this command:

CAL_POINT[0][1]

7. The voltage range is now calibrated. Use the Calibrator to verify calibration.
