3.6.4.2 Two-Point Pressure Calibration – Procedure

To get accurate results, calibrate in conditions where the pressure and temperature are stable.
1. Record the current values for the calibration data:

•

Object 0x2207

00 (Pressure Gain) = GAIN

Default value = 1

•

Object 0x2208

00 (Pressure Offset) = OFFSET

Default value = 0

mbar

2. First calibration point:

a. Apply Pressure (AP1) at 10% of the full-scale pressure (in mbar) and allow the pressure

to become stable.

b. Record the Field Value (FV1) that appears in object 0x6100

01 (Pressure Value).

Record the value in mbar.

3. Second calibration point:

a. Apply Pressure (AP2) at 90% of the full-scale pressure (in mbar) and allow the pressure

to become stable.

b. Record the Field Value (FV2) that appears in object 0x6100

01 (Pressure Value).

Record the value in mbar.

4. Calculate the new values for the calibration data:

•

NEW GAIN = [GAIN] * [(AP1 - AP2) / (FV1 - FV2)]

•

NEW OFFSET = [(OFFSET) - FV1] + [(AP1) * [(AP1 - AP2) / (FV1 - FV2)]]
The value for the NEW OFFSET is in mbar.

5. Write the new values for the calibration data back to the CANopen Object Dictionary:

a. Set object 0x2200

00 (calibration access pin) to 4118.

b. Set object 0x2207

00 (pressure gain) to the NEW GAIN value.

c. Set object 0x2208

00 (pressure offset) to the NEW OFFSET value. The value for the

NEW OFFSET is in mbar.

d. Set object 0x2200

00 (calibration access pin) to 0.

6. Confirm that the new values for the calibration data are correct:

a. Repeat steps 2 and 3.

7. Write the new values for the last and next calibration dates back to the CANopen Object

Dictionary:
a. Set object 0x2200

00 (Calibration Access Pin) to 4118.

b. Set objects 0x2201

00 to 0x2203

00 to the new values for the last calibration year,

month, day.

c. Set objects 0x2204

00 to 0x2206

00 to the new values for the next calibration year,

month, day.

d. Set object 0x2200

00 (Calibration Access Pin) to 0.

8. If applicable, reset the values for the out-of-limit counters (objects 0x2006 to 0x2009).

3.6.4.3 Two-Point Pressure Calibration – Results

For correct operation, the value for the NEW GAIN is in the range 0.9 to 1.1. If the value is not in

this range, this shows either a defective unit or defective calibration equipment.
