T&R DSM200 Micro-ohmeter

The T & R DSM200 is a high current microohmmeter 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. The T & R DSM200 microohmmeter 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.
