This procedure describes the DC gain accuracy adjustments for the probe. You must complete the
DC Gain Accuracy Test
in the
Performance Veri
fi
cation
procedure before making this adjustment. Leave the test setup intact to perform the adjustment.
1.
Set the calibrator output to 2.0 A.
2.
Set the digital multimeter (DMM) to measure DC
volts,
≥
2.0 V range.
3.
Measure the output amplitude on the DMM.
4.
Access the DC gain control through the opening in
the probe head as shown. Adjust the DC gain control
to display 1.000 V, ±10 mV on the DMM.
5.
Disconnect the probe from the calibrator and disable
the output.
