Are some really trying to compare a free harbor fright meter to a fluke clamp on meter?
Egad the clamp on functionality, is the feature. Opening a circuit to measure current, and hoping it is below 10 amps.... no thanks.
The Centek freebies definitely have their place, but not for any serious current measurement, and the voltage drifts. I've had to adjust mine twice so far.
My craftsman Model # 82369 is still on the first set of alkaline batteries( 4 years). Don't have a Fluke to compare it to for voltage or amperage, but amps agree with my shunted meters, and yes, even the freebie centek on a 0.08 amp LED.
