718 Calibration (V2.0 To V3.9); Ma Measure - Fluke 71X Series Calibration Manual

7. Once the pressure has stabilized, push any key on the 718 Calibrator. The display
should read:
CAL
then change to:
CALU
8. Release pressure by venting the system.

9. Push the
calibration. If calibrating vacuum, the display should show:
CAL
10. Make sure the pressure/vacuum switch is in the vacuum position. Forward
(clockwise) is for pressure and backward (counter-clockwise) is for vacuum.
11. Set up the deadweight tester to apply -12.000 PSI.
12. Wait for the pressure standard to stabilize, then push any key.
13. The display should show:
---------------------------
14. The unit will then reset power.
15. The 718 Calibrator is now out of the CAL mode and into the normal mode of
operation. Carefully vent all pressure, push the key to turn the Calibrator off, and
disconnect all pressure fittings.

718 Calibration (V2.0 to V3.9)

mA Measure

1. Hold down both  and  on the 718 Pressure Calibrator. Push and release .
For versions 3.00 and later,  has changed to .
2. The display shows CAL xxx, as long as  and  are pressed. Where xxx is a
number, indicating the number of times the 718Ex has been through the calibration
adjustment. When  and  are released, PASS is displayed. The password is
required before you can enter the calibration mode. The password is 817. Enter the
most significant digit first. The password appears below PASS. Use  to increase
the displayed number,  to decrease it. When the required digit appears, push 
to proceed to the next digit, or the password check. If the password entry was
correct, the 718 will go to the CAL mode. If the password is incorrect, BAD PASS
shows on the display and then the 718Ex returns to the normal operation mode. In
the CAL mode, the 718 should display:
0.000 mA
in the upper display and
CAL 0 mA
on the lower line of the display.
The upper display shows an uncalibrated reading. This reading is approximately
±10 % of full scale of the applied reading. When  is pressed, the calibration value
is calculated relative to this reading. The lower display indicates what function and
point is being calibrated.
3. Connect the test leads from the AUX jacks of the Fluke 5520A to the mA jacks on the
718 Calibrator (black to black and red to red).
