Martindale MM65 Autoranging Digital Multimeter
Speed up your testing with Martindale's MM65 autoranging digital multimeter.
When testing, the MM65 will automatically select the appropriate range, saving time and effort from the user. The meter can be used to test DC voltage to 600V, AC voltage to 60V, AC/DC current to 10A, resistance to 34MΩ and also tests diode/continuity.
Results are shown on the MM65's large 3 and ¾ digit LCD screen which also includes analogue bar graph display. Test selection is made by a rotary dial on the front of the tester.
To conserve battery power the MM65 will automatically power itself off when left idle.
