Functional Check
The functional check will verify the basic operation of the probe functions.
It is recommended that the Functional Check be performed prior to the
Performance Verification Procedure.
1. Return to the factory default settings by:
a. Selecting File, Recall Setup... from the menu bar.
b. Then touching the Recall Default button.
2. Touch the C1 trace label to open the C1 Vertical Adjust dialog.
3. Verify that the probe sensed (ZD Series) is displayed as a dialog tab.
Verification Procedure
A. Output Zero Voltage
1. Leave the probe connected to C1 of the oscilloscope. Set the vertical
sensitivity for C1 to 20 mV/ and the horizontal scale to 1.0 us/.
2. Turn on measurement P1 and set it to measure the mean of C1. Turn
statistics on.
3. Insert the square pin short into the probe input sockets to short the
inputs.
4. Initiate an AutoZero (control on the ZD series dialog tab of C1).
5. Wait an additional 15 minutes, then record the press the ‘Clear Sweeps’
button.
6. Record the mean of P1: mean (C1) as Output Zero on the Test Record.
7. Verify the absolute value of Output Zero is less than the value given on
the probe data sheet.
