1. Set the Function Generator to 50 Hz, sinewave output at 1.7 Vrms with 50 Ω output.
2. Connect BNC male of ProBus extension to DMM #1 using BNC Female to Dual Banana adapter.
3. Using banana patch cords, connect the 'V Source' and 'V Return' terminals of the 500 Turn
Calibration Loop, to the output of the Function Generator using the BNC to Dual Banana Plug
Adapter output. (Refer to Figure 2.)
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 CP150 removed from any signal and the slider returned to the LOCKED position,
degauss the probe by touching DEGAUSS (on the CP150 dialog), then OK.
7. Open the CP150 jaws and position the probe input around the 500 Turn loop. Close and LOCK
the slider.
8. Adjust the Function Generator voltage until the voltage measured at the 'Current Sense'
terminals (DMM #2) is 10 mV ± 0.01 mV. (This corresponds to 10 A at the probe head).
9. Adjust the center variable resistor on the probe head until the voltage measured on DMM #1 is
as close to 10X the voltage measured on DMM #2.
10. Verify that the measured voltage is between 99 mV and 101 mV.
11. Disconnect the probe from the test setup.
12. Re-apply the light blue product label to the probe head using the double-sided tape.
