5. Set both DMMs to measure AC Volt.
6. With the CP031 removed from any signal and the slider returned to the LOCKED position,
degauss the probe by touching DEGAUSS (on the CP031 dialog), then OK.
7. Open the CP031 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 measured at the 'Current Sense'
terminals (DMM #2) is 50 mV ± 0.05 mV. (This corresponds to 10 A at the probe head).
9. Adjust variable resistor VR202 on the PCB until the voltage measured on DMM #1 is as close to
2X the voltage measured on DMM #2.
10. Verify that the measured voltage is between 0.990 V and 1.01 V.
11. Disconnect the probe from the test setup.
12. Re-assemble the compensation box by sliding the circuit board back into the box and inserting
and fastening the two screws.
