CAUTION. To avoid damaging the probe, do not disconnect the probe termination
when measuring high currents. Leaving the probe unterminated can cause a high
voltage to develop in the secondary winding that may damage the current probe
transformer.
1. Using the appropriate adapter, connect the current probe calibration fixture to
the fast rise output of the calibration generator (positive-going transition
± 0).
2. Set the fast rise function:
For the Wavetek 9100, select the Aux (oscilloscope and auxillary), and edge
(step) waveform functions. Set the output for + transition, 100 kHz repetition
rate, and 1V
p-p
output. The signal output is through the BNC connector on
the rear of the signal generator.
Or, if you are using a PG506A, set the function to Fast Rise.
3. Connect the P6021 probe BNC connector to the termination.
4. Connect the P6021 termination to the oscilloscope Ch 1 input.
5. Set the P6021 termination sensitivity to 2 mA/mV.
6. Pulling back on the probe slide switch, connect the probe to the current
probe calibration fixture.
Ensure that the current is flowing in the correct direction; the minus sign
should be near the outside and the plus sign should be near the connectors, as
shown in Figure 6. (The figure shows the probe slide switch held open so
that the plus and minus signs are visible. When you close the probe, the front
portion with the markings will disappear inside the calibration fixture.)
