Sin Embargo (Nevertheless)
VERIFY the shunt ma versus the display. A good voltmeter (not a Frightening Harbor model) can be placed across the shunt and measure mv versus display. This is part of the reason I went with a 4-1/2 digit DMM.
Only the FIVE DIGIT DROK ammeter is accurate. I do not like the 3-1/2 digit Drok ammeters. Now I see the 5-digit is no longer available. Figures.
These rice a roni meters use off-standard ma shunts. It gets tough finding a genuine MANGANIN shunt for them. The shunts I got with Chinese meters are +- 1.3 amps error at 100-amps. Not the meter I'm talking about - the SHUNTS. Means a lot when an ampere hour or kWh function is in use. Check those shunts!
