10. Attach the differential probe input lea ds (wit hout attachment
accessories) by sliding the banana plug of the leads onto the
binding posts metal sleeves on the Modified BNC adapter
(see Figure 13).

WARNING. To reduce the risk of electric shock, ensure the generator
output is disabled before modifying/disconnecting test setup or
connect ions since exposed metal may at a hazardous potential. It is
recommended that the generator output amplitude be reduced to
minimum prior to disabling the output.
11. Set the probe to 500X (out). Set the generator for a 100 V and
1 kHz standard amplitude output (AUX, square wave, 1 MΩ
load).
12. Reduce the ampli tude on the generator to minimum then enable
the output.
13. Adjust the zero offset on the compensation box of the probe for
zero offset.
14. Record the DC amplitude of the square wave (∼100 V) and divide
1/1000
th
of this into the amplitude of just the oscilloscope (refer
to step 6). Verify that only the probe gain accuracy
is ᐔ3%.
