Calibration Manual
54
mA Loop Power Verification (718 Only)
1. Hold down both LOOP POWER keys ( and ) at the same time until the
screen reads:
---------- LOOP mA
then release the keys.
2. Apply 1 kΩ to the mA jacks from the decade box or other resistor source. The
display should read over 19 mA but less than OL.
3. Push
to turn the calibrator off.
Sensor Jack Verification
1. Make sure nothing is connected to the sensor port of the calibrator. Push
to turn
the calibrator on. The display should read:
----------
then change to:
0.000
2. Plug the Fluke Pressure Module into the sensor port of the Fluke 718. The display
should change to:
----------
A pressure value should appear on the screen after all of the calibration constants
have been downloaded.
3. Disconnect the Fluke Pressure Module and push to turn the calibrator off.
Display Verification
1. Push and hold the
key and then push and release the green key. This locks the
718 in a mode where all display segments are on. All segments will stay on until the
key is released.
2. Check to see that all segments of the display are showing.
3. Turn the calibrator off. The 718 and 718Ex verification test is now complete.
719 Verification
This procedure is appropriate for the 719.
Display Verification
1. Push and hold . This locks the 719 in a mode where all display segments are on.
All segments will stay on until is released.
2. Check to see that all segments of the display are showing.
Pressure Verification
WWarning
To avoid a violent release of pressure or vacuum, always
depressurize the system slowly using the pressure/vacuum
release control before detaching any pressure line.
1. Carefully attach the pressure fitting of the deadweight tester to the pressure port of
the Calibrator.
Note
The use of TEFLON tape at the pressure fitting strengthens the seal.
