Martindale MM39 Standard Digital Multimeter Auto Ranging - Front

Description

The Martindale MM39 is an autoranging, portable multimeter that can be used to carry out DC voltage, AC voltage, AC current, DC current, resistance, diode and continuity testing procedures.

When measuring voltages, the MM39 features measurement range of 0.1mV to 600V on both AC/DC, with five ranges available. When measuring current, the device features range of 0.01A to 10A, and when measuring resistance the MM39 has measurement range of 0.1 to 20MΩ. It also features a continuity buzzer which will sound at less than 25Ω.

Using the MM39 is straightforward. The device features a rotary dial for quick selection between different available parameters, and it also has a button for changing the range, and a button for holding the data currently displayed on screen. Above this there's also a 3.5 inch LCD screen which relays testing results.
