This is a stable, low power consumption, and high accuracy 3 1/2 digits (2000 counts) leaking current meter for automobile. Leaking current for automobile is generally as small as milliamps, which is hard to measure by clamp meter. By plug this meter with the fuse box, user is able to measure leaking current as small as 1 mA.
