Ma Source Verification - Fluke 71X Series Calibration Manual

mA Source Verification

1. Turn ON the 719 Calibrator.
When the display indicates a pressure and current value, for example:
0.00 PSI
0.000mA
2. Push  three times, the lower display should read:
Source 4.000mA
The lower display will flash 4.000mA / OL until the circuit is complete.
3. Connect a test lead from Red Calibrator mA terminal to the Fluke 8508A I+ terminal.
4. Connect a test lead from the I-terminal of the Fluke 8508A to the Calibrator COM
terminal.
5. Set the 8508A to DC mA.
6. Change the output mA value by pressing  (Steps are 4 mA, 8 mA, 12 mA, 16 mA,
20 mA), or scroll the mA output value between 0...24 mA using  or .
7. Verify that the current readings on the Fluke 8508 are within the limits shown in
Table 70.
8. Disconnect the test leads and turn off the 719 Calibrator.
