Do measure ac voltage in more than +10v V multimeter from dc V source, HT118A voltage display goes crazy and fails in this situation, but reconnecting multimeter to mv ac works.
It's likely a software or firmware issue. This and the HT118A are the only two I've tested that have that problem. Everything else I have tested measures the frequency, voltage and duty cycle correctly.
I have 2 pieces of HT118A, they are 100% identical, about 1 year production date difference. Not heard about firmware update for cheap measurement equipment. Measuring mixed voltage/signal makes the difference visible between pricey and cheap equipment. Some cheap meters show high voltage results even one probe not connected.
I think they made this one badly, but the KM601 has a very fast autorange, which is important to me when measuring resistors
I wouldn't call it bad, but the lack of the REL function is an major achilles heel of this meter. Far and away it's biggest problem.

Evidently wasn't done with the HT188E either.
