I agree about the trouble light. It would be a lot cheaper to buy if the OP doesn’t have access to a good analog meter.
It is a right term although “small load” can also be used. The load drawn by an analog meter would be sufficient to draw down the residual voltage.
We had a transformer returned to us at the factory by a utility once. It was a large three phase with a 4 position switch on the front, H1 to coil, H2 to coil, H1 and H2 to coil and Open. With H1 to coil selected, H2 is open, but they were measuring 460 volts on H2 with 34,500 volts applied to H1 using a digital voltmeter. When we tested with an analog voltmeter, nothing was detected. The wire going from the switch to the H2 bushings was picking up an induced voltage from the coil, but being as far from the coil as it was, and not having a coiled section, the current was unmeasurable. Digital voltmeters do not load down a circuit where an analog meter does to some degree.
