The DO7 digital microhmmeter is a practical instrument for low resistance measurement, ideal for Utilities use in the workshop, field or test facilities. It is of rugged construction, contained in a sealed ABS plastic case with lid and carrying handle.

The DO7 digital microhmmeter has many advanced features, including protection up to 415 volts rms at the measuring terminals, digital calibration and long scale length, 6000 count. Rechargeable batteries means real portability with more than 1 hour of continuous operation on the lowest ranges(10A), and 20 hours on all others. The internal charger will boost charge to 90% of full charge, switching automatically to a trickle maintenance charge. Warning LEDs illuminate when an open circuit lead condition is detected.

A front panel socket provides a serial RS232 output for connection to an external printer or PC, and a socket is also provided for the connection of an external start switch, e.g. a foot switch. TheDO7 is supplied ready for use with batteries, mains cord and test leads, no extras are normally necessary. For special lead sets we offer a variety of different styles which are listed on the accessories page, together with calibration standards.

Includes:
Mains cord
Calibration certificate
Measuring leads with Kelvin Clips
