Figure 39. Current Sensor Information
Calibrate the Sensors
Test port (ATM and 3,000 psi). See Figure 40.
Note
Fluke Calibration does not recommend to do this adjustment at a
maximum pressure <1500 psi to ensure best sensor alignment. If
you do not have a 3000 psi module, use the highest-rated module
that you have.
1. Install the highest-range PMM that you have and make it the fixed range.
2. Set the PMM measurement mode to Absolute.
3. Apply a supply pressure of 110 % to 115 % FS of your highest-range
PMM.
4. Install a shutoff ball valve on the test port and leave it open.
5. Vent the system.
6. Use a reference barometer to read the absolute ATM pressure in the
units and type CAL:PRES4:VAL1 xx.xx (xx.xx = value in units must be
absolute) on the terminal.
7. Close the shutoff valve on the test port.
8. Set a pressure to control at FS of your PMM.
9. Read the absolute PMM pressure and type CAL:PRES4:VAL2 xx.xx
(xx.xx =value in units must be absolute) on the terminal.
10. Type CAL:PRES4:SAVE on the terminal.
