Description

Martindale MM65 Autoranging Digital Multimeter

The MM65 is an autoranging digital multimeter which measures AC and DC voltages up to 600V, and AC and DC currents of up to 10A. It measures resistance to 34MΩ and has a diode test and an audible continuity test which sounds below 35Ω.

It has a 3¾ digit LCD screen and it will display the results as digital numerical values and on a 34 segment analogue bar graph. The MM65 also has an auto-power off feature and on screen low battery indicator.

The Martindale MM65 Is Supplied With:

  • Martindale MM65 Autoranging Digital Multimeter
  • TL16 Test Leads
  • Magnetic Strap
  • 1 x Spare Fuse
  • 9V Battery (Installed)
  • Instruction Manual

Key Features:

  • High accuracy measurements
  • AC/DC voltage measurements
  • AC/DC current measurements
  • Resistance testing
  • Continuity evaluation
  • Diode testing
  • Analogue bargraph
