The Cropico DO7 digital micro ohmmeter 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 Cropico DO7 casewith lid and carrying handle.

The DO7 is an accurate bench/portable Digital Ohmmeter for the measurement of resistance in the range 0.1μΩ to 60Ω. It offers you the four terminal resistance measurement method to eliminate the effect of lead resistance. The measured values are displayed on a 4-digit LCD display; an overflow of the selected range is also indicated.

The measurement is true 4 terminal, using the Kelvin principle. A stable current is produced across the resistance to be measured via the C terminals, and the voltage drop across the Rx is measured at the P terminals. This potential drop is then compared against the voltage drop across internal standards. The ratio of these is then converted to the resistance value of Rx and displayed in ohms on the digital display.

The Cropico DO7 digital micro ohmmeter has many advanced features. Rechargeable batteries means real portability with more than 1 hour of continuous operation on the lowest ranges(10A), and 20 hours on all others. Warning LEDs illuminate when an open circuit lead condition is detected.

High accuracy from 600 microhms to 60ohms ranges.
LED display for daylight viewing.
