HVD3000 Series High-Voltage Differential Probes Operator's Manual

Preliminary Procedure

1. Connect the probe under test to the female end of the ProBus Extension Cable. Connect
the male end of the ProBus Extension Cable to channel 1 (C1) of the oscilloscope.
2. Turn on the oscilloscope and allow at least 30 minutes warm-up time before performing
the Certification Procedure.
3. Turn on the other test equipment and allow these to warm up for the time recommended
by the manufacturer.
4. While the instruments are reaching operating temperature, make a photocopy of the
Performance Verification Test Record (following this topic), and fill in the necessary data.

Certification Procedure

1. Set the function generator to sine wave, 70 Hz, and an output voltage of approximately:
7 Vrms (into a high impedance output) for HVD310x and HVD3206
l
37 Vrms for HVD3605
l
2. Set the DMM to measure AC Volts.
3. Connect the function generator output to the DMM, using a BNC cable and a female BNC
to dual banana plug adapter.
4. Adjust the function generator output voltage until the DMM reads:
7 V ±0.01 V for HVD310x and HVD3206
l
37 V ±0.01 V for HVD3605
l
5. Record the DMM reading to 1 mV resolution in the Test Record.
6. Disconnect the BNC cable from the function generator and from the BNC-to-banana plug
adapter on the DMM. (Leave the banana plug adapter connected to the DMM).
7. Connect the BNC connector from the probe extender cable to the BNC-to-banana plug
adapter on the DMM.
8. Connect the insulated banana plug adapter to the function generator.
9. Using the insulated banana couplers, connect the positive lead (red) of the probe under
test to the positive output of the BNC-to-banana plug adapter and the negative lead (black)
to the negative or return output.
10. Set the oscilloscope scale factor to:
20 V/Div for HVD310x and HVD3206
l
50 V/Div for HVD3605
l
11. Record the DMM reading to 0.01 mV resolution in the Test Record.
12. Multiply the measured output voltage recorded in step 11 by the actual probe attenuation
factor, then divide this number by the function generator output voltage (probe input
voltage) recorded in step 5. Subtract 1 from this number and multiply the result by 100 to
