Ac-leakage tester
has 10-µA resolution
The Model 380943 ac-leakage-current clamp-on tester has a 10-µA
resolution and a 1% accuracy for low-ac-current measurements. It features
a 4,000-count display that includes a 40-segment analog bargraph. Functions
include ac-voltage and resistance measurements, continuity, max/min and
data hold, and auto power off.
The tester's clamp jaws open to 1.2 in. and are shielded to minimize
the effect of stray magnetic fields. The unit has a 40-Hz to 1-kHz frequency
response and provides a selectable 50- or 60-Hz filter circuit to eliminate
high-frequency noise and harmonics. ($299–stock.)
