Jeremy,
Tune the capacitor very slowly and use a non-metallic tool. The null is
sharp and deep.
You must have a good 50 ohm dummy load connected.
You may want to take your external wattmeter out of line to do the nulling.
The actual voltage will depend on the power level, at 5 watts it should
be less than 10 mV, but you should be able to get it below 15 or 20 mV
if the power is 10 watts. If you are using 20 watts or more from the
KPA100, then your 30 mV is probably OK.
Ideally, the voltage should go to zero, but being practical, one may not
be able to adjust the capacitor in fine enough increments to achieve
that goal.
