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 (located in Appendix A), and fill in the necessary
data.
Procedure
1. Set the function generator to sine wave, 70 Hz, and an output voltage of approximately
7.00 V rms (into a high impedance output).
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 7.000 V ±0.01 V.
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 under test 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
(
Blue
) to the negative or return output.
10. Set the oscilloscope scale factor to 20 V/div.
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 1000 and 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 get the error in percent:

13. Record the answer to two significant places (±x.xx%) on line 13 in the Test Record.
14. Verify that the error
≤
1.00%.
15. Decrease the oscilloscope scale factor to 5 V/div.
16. Record the DMM reading to 0.01 mV resolution in the Test Record.
