The DO7e is a very rugged yet compact and portable digital microhmmeter for the measurement of low resistance. Using a rechargeable sealed lead acid battery with built-in charger the DO7e is capable of measuring with a current of 10Amps on the lowest range.

The DO7e has been designed with the latest solid state and microprocessor techniques to ensure the very best in measurement reliability, and features. Automatic range selection, forward and reverse current measurements with auto average and a remote start socket are all included as well as an energy saving power down mode.

The DO7e incorporates many advanced features, including protection up to 415Vrms at the measuring terminals, digital calibration and long scale length 6000 count. The DO7e is built into a rugged carrying case with rechargeable batteries giving real portability.

Six measuring ranges from 600Ω to 6mΩ and the long scale length, 6000 count, will ensure high measurement resolution. Resistance down to 1µΩ can be measured. The use of a high capacity sealed lead acid battery enables a measuring current of 10A on lowest measuring range.

The Battery charger is built in and the auto switch off circuits ensures the maximum battery life, with over 2000 measurements at 10A from a single charge.

Forward and reverse current measurements are available as well as the automatic average of the two readings, this ensures maximum accuracy and eliminates errors due thermal emf. The measuring ranges may be manually selected or the DO7e can be set to select the correct range automatically
