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 Temperture measurements. The MA440 Series pocket-sized meters are fully loaded with multimeter functions and built-in non-contact voltage (NCV) detector to meet your application needs! Common Features • Pocket-sized meters with 1.2" (30mm) jaw size fit Features • conductors up to 500MCM Model MA440 (9 Functions) - AC Current • Built-in Non-Contact Voltage (NCV) detector • MultiMeter functions include Resistance, - True RMS • Model MA443 (10 Functions) Capacitance and Frequency - AC Current • Relative Mode for Capacitance - Type K Temperature • Data Hold freezes reading on display - Built-in bright flashlight • Auto Power Off with disable and Low Battery indication - Max/Min • Large backlit LCD display • Complete with test leads, three AAA batteries, and - True RMS pouch; MA443 and MA445 also includes a general - AC/DC Current purpose Type K Temperature probe* - Type K Temperature * General purpose Type K probe included does not measure full range of meter capability.
