4. Set the 5500A output to 0 V dc and select O.
5. Press any key until the Loop Calibrator’s display
changes.
6. When the display shows
28.000 V, set the 5500A
output to 28 V dc.
7. Press any key until the Loop Calibrator’s display
changes.
8. When the display shows
HHHH, place the 5500A
in the STANDBY mode.
9. Press any key until the Loop Calibrator’s display
changes.
10. Turn the Loop Calibrator’s rotary switch to mA.
11. Press any key until the Loop Calibrator’s display
changes.
12. Connect the test leads from the
AUX terminals of
the Fluke 5500A to the terminals on the Loop
Calibrator (black to COM and red to [+]).
13. Set the 5500A output to 0 mA dc and select
O.
14. Press any key until the Loop Calibrator’s display
changes.
15. When the display shows
20.000 mA, set the
5500A output to 20.000 mA.
16. Press any key until the Loop Calibrator’s display
changes.
17. When the display shows
HHHH, place the 5500A
in the STANDBY mode and remove any test lead
connections to the Loop Calibrator.
18. Short the terminals and press any key. The Loop
Calibrator now enters a self-source calibration
adjustment process. The output must be shorted
during this step.
The Loop Calibrator resets power when the self-
source calibration adjustment is complete.
Note
The Loop Calibrator resets to the current
source function prior to entering the self-
source calibration procedure, i.e., 0.000 mA
for 0-20 mA loop or 4.000 mA for 4-20 mA
loop.
19. Remove all connections and place the rotary
switch of the Loop Calibrator to
OFF.
The calibration procedure is now complete.
