Functional Test Procedure

This procedure should be performed to confirm the basic operation of the probe, or to aid in
determining the source of a problem, rather than to verify the accuracy of the probe. You can
perform the Functional Test without removing the probe covers.

Required Equipment

Other than a Teledyne LeCroy oscilloscope, no special test equipment is required for the
functional test.

Test Procedure

1. Connect the HVD3102/HVD3106 to any vertical channel on the oscilloscope.
2. Select the channel to which the probe is connected.
3. Press the AUTO ZERO button in the user interface menu.
4. If necessary, adjust the OFFSET to 0.000 V.
5. Using accessory clips, attach the red clip to the + CAL out and the black clip to the ground
post of the CAL out signal. For oscilloscopes with the CAL signal on a BNC connector, a BNC-
to-Banana adapter (e.g., Pomona model 1296) may be used.
6. Press AUTOSETUP.
7. Set the sensitivity of the probe to 1 V/Div.
8. Set the CAL output to 1 Vp-p square wave.
9. Verify that the displayed square wave is 1 Vp-p centered at +0.5 V.
10. Reverse the accessory leads on CAL out and verify that the displayed square wave is still 1 V,
but is now centered at –0.5 V.
11. Change the COUPLING on the user interface menu to Grounded to verify that the signal
disappears and that the trace is still centered on the screen.
12. Verify that the probe attenuation shows x100 for HVD3102 or x50 for HVD3106.
13. Set the VOLTS/DIV to 100 V.
14. Verify that the probe attenuation now shows x1K for HVD3102 or x500 for HVD3106.
