Procedures: Pressure Module
c. Check the error is within limits. Refer to Table 12 - 15 or Table 12 - 16.
12.14 Procedures: Pressure Module
Note: This procedure is suitable for PM 620, PM 620T or IDOS UPM pressure modules.
Do the procedure as follows:
1. Assemble the pressure indicator with the necessary pressure module.
2. Connect the instrument to the pressure standard.
3. Let the equipment get to a stable temperature (minimum: 1
hour since the last power on).
4. Use the calibration menu (see Section 12.1) to do a two-point pressure calibration (absolute
sensors) or three-point pressure calibration (gauge sensor).
•
- FS, Zero and +FS for gauge sensors.
• Zero and +FS for absolute sensors.
Note: If software version requires a three-point calibration for an absolute sensor, use points
at 0, 50% and +FS or three-point calibration. Refer to Table 12 - 17 or Table 12 - 18.
