HVD3000 Series High-Voltage Differential Probes Operator's Manual

Functional Test Procedure

This procedure should be performed to confirm the basic operation of an HVD3000 series
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.
Other than a Teledyne LeCroy oscilloscope, no special test equipment is required for the
functional test.
1. Connect the probe to any vertical channel on the oscilloscope.
2. Select the channel to which the probe is connected.
3. Touch AUTO ZERO on the probe dialog.
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 channel setup dialog 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 the following:
x100 for HVD3102
l
x50 for HVD3106 and HVD3206
l
x200 for HVD3605
l
13. Set the VOLTS/DIV to 100 V.
14. Verify that the probe attenuation now shows:
x1K for HVD3102
l
x500 for HVD3106 and HVD3206
l
x2K for HVD3605
