Extech Instruments MA443 400A True RMS AC Clamp Meter NCV Datasheet

Extech Instruments MA443 400A True RMS AC Clamp Meter   NCV Datasheet
PRODUCT DATASHEET
MA440 Series 400A
Clamp Meters + NCV
Three models to choose from, with or without True RMS
and AC or AC/DC Current functions. Choose True RMS
model for accurate readings of non-sinusoidal waveforms,
model with DC Current function for automotive
applications, or model with Type K function when
applications require Temperature measurements. The
MA440 Series meters are fully loaded with multimeter
functions and built-in non-contact voltage (NCV) detector
to meet your application needs!
