Portable Digital Microhmmeter LOM-DO7e

> True 4 terminal measurement eliminates lead resistance errors
> 10 amp measuring current
> Rechargeable batteries with built-in charger
> Measuring range 6mW...600W
> Resolution 1.0 mW on 6mW range
> Auto and manual range selection
> Auto Power off for longer battery life

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 Microhmmeter is capable of measuring with a current of 10Amps on the lowest range. The DO7e Microhmmeter 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 series 4000 digital ohmmeters offer true portability without any sacrifice to accuracy or functionality. These ruggedly constructed ohmmeters are housed in a stylish plastic case with an easy to use keyboard, the measured values are displayed in large LCD panel. Many advanced measurement features are included, Long scale length 4000 count, Auto average of forward and reverse current measurement,

true zero of measured value and temperature compensation (model 4001).
Rechargeable batteries with automatic power off ensures the best
possible battery performance.
Technical Data:
The series 4000 portable digital ohmmeters are a practical range of
instruments for low resistance measurement, ideal for use in the
workshop on site or in the laboratory. Constructed in a hand portable
plastic case sealed to IP54 standard the series 4000 offers many
advanced features, including auto reverse of measurement current, which
eliminates errors due to thermal emf. A true zero button, which will allow
the measurement to be set to zero. Protection up to 415Vrms at the
measurement terminals and automatic temperature compensation
(model 4001).
