Best For checking Amp draw: GTC open Jaw Clamp Meter

Buy on Amazon

The gtc open jaw clamp meter should be able to handle its purpose and duties with ease. This unit has a long narrow clamp that opens in the middle, perfect for getting in tight spaces to see what the line is doing. The electronics that measure DC current are sensitive to temperature fluctuations and the offset (zero value) will change as the instrument cools or warms. An automatic zero feature keeps the jaws calibrated even when the currents being measured are minuscule. It's great for reading battery current without cutting into the circuit.

The clamp size is perfect for most near any application. It is temperature sensitive, so it does require zeroing occasionally, its only drawback. It's all in accuracy and post-zeroing drift.
