T&R Test Equipment is a market leader in the field of high current micro-ohmmeters, manufacturing durable, accurate and user friendly units. The DSM 600 is a high current micro-ohmmeter suitable for measuring very low resistances in a wide range of applications. The unit is equally suited to commissioning, maintenance, and production line environments. Contact resistances in circuit breakers, switch panels, isolators, and busbar joints are all easily and safely measured.



  • 0 to 600 Amp DC test current.
  • 0.1Ω resolution.
  • mV. A, and Ω displayed simultaneously.
  • Direct Ohms reading at any current.
  • Large back-lit liquid crystal display (LCD).
  • Thermal and over-current protection.
  • Compact and portable.
  • Isolated RS-232 interface for printer or PC.
  • 90 Volts to 264 Volts 50/60Hz supply voltage.
  • High quality 3-meter output lead set - supplied as standard.


  The DSM 600 is simple to operate, only requiring the user to switch the output 'ON' and set the test current. Selection of all ranges is fully automatic, and current, voltage and resistance are displayed simultaneously at all times. The resistance is calculated from the test current and sense voltage, and there is no need to set an exact test current to guarantee an accurate test result. To assist the user, all readings are held on the display when the output is switched 'OFF'

Connecting the DSM 600 to a PC running the optional DSMlog software adds data capture and reporting functions to the unit, allowing test results to be exported directly to Excel or saved to a file

All results are time stamped, and comments may be added to each test. Data capture can be controlled from the PC, and the resistance of a test object can be monitored over a period of time.

Alternatively, connecting a printer allows all of the test parameters to be printed automatically whenever the reading is held
