The DO7e is a very rugged yet compact and portable digital
micro ohmmeter 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 10 Amps
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.
Typical applications: Rotating Machines, Switch contacts,
Electrical connectors, Crimped Joints, PCB Track, Cable joints,
Earth Bonding, Small transformer windings,Heating Elements,
Quality of wrapped joints, quality of solder joints and Cable
lengths
