Fluke 80i-1010 - Performance Verification

| BALANCE Adjustment
7. Use the following procedure to make the final GAIN calibration:
a. Remove the 10-turn coil and connect the 50-turn torroid coil to
the amplifier output.
Set the calibrator and amplifier controls to source 3A at 50 or 60
Hz in the 50-turn coil, thus producing 150A turns.
Locate R7 in the probe handle (see Figure 4). Remove the
sealing compound if necessary to access the GAIN adjustment.
Clamp the probe around the center of the coil and allow the jaws
to close with a snapping action to properly seat the mating
surfaces.
Set the voltmeter function and range to accommodate a display
of 200 mV ac.
Adjust R7 (GAIN) so that the voltmeter reads 150 mV +0.1 mV.
Set the amplifier to standby. This completes the final GAIN
calibration procedure.
PERFORMANCE VERIFICATION
Required Equipment
The equipment required forthe performance verification procedure is the
first four items listed in Table 2.
Setup Procedure
Perform the following steps to set up for DC and AC Operation verifica-
tion procedures:
a
Connect the 50-turn toroid coil to the Transconductance Amplifier
output.
Connect the DC/AC Voltage Calibrator output to the amplifier input.
3. Turn both instruments on and allow sufficient warm-up time for stable
operation.
Perform steps 1 through 5 of the BATTERY TEST procedure.
