Cropico DO7e Micro Ohmmeter
RUGGED DIGITAL MICRO OHMMETER FOR
LOW RESISTANCE MEASUREMENT
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.
True 4 wire measurement eliminates lead resistance
6 push button ranges 6 milli ohm to 600 ohm
Resolution 1 micro ohm on 6 milli ohm range
Auto ranging
10 Amp measuring current on lowest range
0.8" LED Display daylight viewable
Input protection up to 415 Volts rms
Forward and reverse current measurement
Auto average of forward and reverse measurement
Auto power off
Mains / rechargeable battery operation
Digital calibration pass code protected
