On a side note, when using a milliameter in the cathode leg (an analog meter that is), it's not necessary to put a cap across the meter, contrary to popular belief.
If trying to use a digital meter for K current, all bets are off. Digitals tend to go nuts on spikey or complex waveforms, and the reading ain't to be trusted, cap or no cap.

Digital meters have their place, but not for certain applications. They take too long to make up their mind, when instant readings have to be taken.
