- Resolution of 100 nano ohm on 2 milli ohm range
- 2 push button ranges 2 milli ohm… 200 kilo ohm
- Dry circuit measurement: 18mV limited
Covering a wide range of measurements from 1 micro ohm to 200 kilo ohm, the DO6 ohmmeter is a comprehensive ohmmeter with many features incorporated as standard.
These benefits include manual and automatic range selection; temperature compensation for copper, referencing the measurement of copper to 20°C; voltage limiting facility for those wishing to measure switch contact resistance to International Standards.
