Step 6. Ensure that the pressure generated by the Standard on the Static port is still 60.000
inHg. Select item '2' using the keypad on the remote unit and then enter the value 60.000 in
item 2. This indicates the Pt full scale point for the calibration. It is the "As Left" Full Scale
Test Point for Pt in Fig. 6.1.
If you make an error while entering data, press "CLR". Do not press "CANCEL". You may
re-enter the value any number of times.
Step 7. Now generate a pressure of 1.000 inHg with the Standard. Allow the pressure to
stabilize for 2 minutes, select item '1' using the keypad on the remote unit and then enter the
value 1.000 in item 1. This indicates the vacuum point for the calibration. It is the "As Left"
Vacuum Test Point for Pt in Fig. 6.1.
If you make an error while entering data, press "CLR". Do not press "CANCEL". You may
re-enter the value any number of times.
Step 8. On the keypad of the remote unit, press "PREV SCREEN". The display will return to
the Main Screen.
WARNING: If you press "CANCEL" the calibration adjustment will become void.
Step 9. The calibration adjustment is now complete for the Pt output. Proceed to the next
step to verify the calibration.
Step 10. Verify the calibration by generating pressures in approximately 10% increments and
noting the actual values for Pt at each pressure point. Your calibration sheet will appear as
shown in Figure 6.1.
