Mine arrived last week, and I tested it against other ammeters, not knowing which one to believe. They were generally within 10% of each other. My Sears clampmeter needs new AAA alkalines as they are in the 1.21v range and Nimh's in it had readings off by 25% when i first got it.
The bayite only has a 0.2a resolution and indicates negative amperage not with a - sign before the number but a period after the decimal placed number.
I found the voltage to be 0.2v out of line with reality, there is no voltage calibration potentiometer.
What I want to find is some nice flat 3 wire ribbon type cable. like which came with the device, so I can locate the sensor further away from display, cleanly. The 6.5 feet provided is not enough, given my intended locations.
I intend to measure total alternator current with it with display visible from drivers seat, initially, but will likely move sensor to another wire to display amps into and out of battery after enough data is collected.
The sensor says it is only good to 140F so no engine compartment mounting locations.
I wish the display were red instead of green, but Oh well.
