Verifying Calibrator Operation 6
6-11
3. Verify the Calibrator’s ac voltage calibration performance at each voltage point listed
in Table 6-11. Deviations should not exceed the specified limits.
4. Set the Calibrator’s output voltage to 10 V ac with a frequency of 400 Hz. Connect a
standard counter to the voltage output terminals of the Calibrator. Verify the
Calibrator’s output frequency is within the specifications listed in Table 6-11.
Deviations should not exceed specified limits.
DC Voltage Calibration Verification (5320A/VLC Models Only)
1. Select the dc voltage calibration function on the Calibrator.
2. Connect a standard multimeter to the appropriate output terminals of the Calibrator
and select the dc voltage function. Set the appropriate parameters on the standard
multimeter to meet its best accuracy.
3. Verify the Calibrator’s dc voltage calibration performance at each voltage point listed
in Table 6-12. Deviations should not exceed the specified limits.
Meter Verification
1. Select the meter function on the Calibrator. Connect the voltage output terminals of
the multifunction calibrator to the Calibrator’s Meter V and COM input terminals.
2. Verify the Calibrator’s Meter function measures ac and dc voltages within the
specifications listed in Table 6-13. Deviations should not exceed specified limits.
3. Select the Meter function on the Calibrator. Connect the current output terminals of
the multifunction calibrator to the Calibrator’s Meter A and COM terminals.
4. Verify the Calibrator’s Meter function measures ac and dc currents within the
specifications listed in Table 6-14. Deviations should not exceed specified limits.
At any point in the verification, if a Calibrator function does not fall within the lower and
upper limits, the appropriate function and range should be recalibrated. It is not necessary
to recalibrate all the functions, just the one that does not meet the specification. Refer to
the 5320A Service Manual or contact Fluke for calibration.
Note
AC voltage frequency and distortion cannot be adjusted in the Calibrator.
Hipot Leakage Current Verification
1. Press M.
2. Select the Mode softkey and change the mode to HIPOT LC.
3. Connect the current output of the multifunction calibrator to the Calibrator’s A and
COM input terminals.
4. Verify the Calibrator’s HIPOT LC function measures ac and dc currents within the
specifications listed in Table 6-15. Deviations should not exceed specified limits.
