CP030 Current Probe
5-4 ISSUED: September 2005 CP030-OM-E Rev B
2. Remove the CP030 from the oscilloscope 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 Calibra-
tion Loop to the voltage inputs of DMM #2.
5. Set both DMMs to measure AC Volt.
6. With the CP030 removed from any signal and the slider
returned to the LOCKED position, degauss the probe by
pressing the DEGAUSS button (located in the CP030 dialog),
then press OK.
7. Open the CP030 slider and position the probe input around
the 100 Turn loop. Close and LOCK the slider.
8. Adjust the Function generator voltage until the voltage mea-
sured at the ’Current Sense’ terminals (DMM #2) reads
50 mV ±0.05 mV. (This corresponds to 10 A at the probe
head).
9. Record the voltage measured by DMM #1 on the Test
Record.
10. Verify that the measured voltage is between 0.989 volt and
1.011 volt.
