PRODUCT DATASHEET

MA140/MA145

True RMS 300A

Mini Clamp Meters + NCV

Model MA140

AC Current

Model MA145

AC/DC Current

Choice of AC Current or AC/DC Current model with 0.8" (22mm) jaw size and high accuracy. Smart Auto Sense feature enables

the MA145 to recognize the input (within a given function) and automatically switch to the correct mode of operation (i.e. AC to

DC Current measurement). Built-in Non-Contact Voltage (NCV) Detector allows for quick detection of live voltage.

Features

•

True RMS for accurate readings of noisy, distorted or

non-sinusoidal waveforms

Model MA140

— AC Current

Model MA145

— AC/DC Current and Zero function for

accurate DC measurements

•

Built-in Non-Contact Voltage (NCV) detector

Inrush current measurement

6000 count backlit LCD display

Smart Data Hold: Audiovisual alert when a new

reading exceeds 50 digits of a held reading

Low battery indicator and Auto Power Off feature

CAT III-600V safety rating

Complete with carrying case and two LR44 batteries

•

Compact 0.8" (22mm) jaw size accommodates

conductors up to 300MCM and allows measurements

in tight locations

•

Unique Smart Auto Sense feature

Low Pass Filter (LPF) for accurate measurement of

variable frequency drive signals
