CP03x/CP03xA Current Probes
1. Set the Function generator to 50 Hz sine wave, output voltage at 3 Vrms with
50Ω output.
2. Remove the probe from the instrument and reconnect using the ProBus
extension cable. Connect the BNC male connector of the ProBus extension to
DMM #1 using a BNC Female to Dual Banana adapter.
3. Using Banana Patch cords and the BNC to Dual Banana Plug adapter, connect
the 'V Source' and 'V Return' terminals of the 100 Turn Calibration Loop to the
output of the Function Generator.
4. Connect the Current Sense terminals of the 100 Turn Calibration Loop to the
voltage inputs of DMM #2.
5. Set both DMMs to measure AC Volt.
6. With the probe removed from any signal and the slider returned to the LOCKED
position, degauss the probe by pressing the DEGAUSS button.
7. Set the current probe channel sensitivity to 1 A/div.
8. Open the probe slider and position the probe input around the 100 Turn loop.
Close and LOCK the slider.
9. Adjust the Function generator voltage until the voltage measured at the 'Current
Sense' terminals (DMM #2) reads 50 mV ±0.05 mV. (This corresponds to 10 A at
the probe head).
10. Record the voltage measured by DMM #1 on the Test Record.
11. Verify that the measured voltage is between 0.989 volt and 1.011 volt.
Performance Verification Test Record
Permission is granted to photocopy the following page and record the results of the
performance verification procedure on the copy. File the completed record as required
by applicable internal quality procedures.
Results recorded under "Test Result" are the actual specification limit check. The test
limits are included in all of these steps. Record other measurements and intermediate
calculations that support the limit check under "Intermediate Data".
