Martindale MM39 AutoRanging Digital Multimeter

The Martindale MM39 is an auto-ranging multimeter with a large rotary switch for easy selection of the required test function, even when wearing gloves. There are two test buttons, one to lock the range and the other to hold the results which are displayed on a 3½ digit LCD screen.

The main test functions are AC voltage, DC voltage, DC current and resistance. The MM39 measures both AC and DC voltage between 0.1mV to 600V and AC and DC current between 10mA and 10A. It also has a diode tester and an audible continuity tester which sounds when connected to a resistance less than 25Ω.
