Introduction to the Cropico DO7e Series:

• The DO7e is a practical low cost micro ohmmeter for low resistance measurement, ideal for utilities in the workshop, field or test facilities. This micro ohmmeter is of rugged construction, contained in a sealed ABS plastic case with lid and carrying handle.
   

• The DO7e microhmmeter has many advanced features, digital calibration and long scale length, 6,000 count. The measuring ranges may be automatically or manually selected.
   

• Automatic Power Off ensures maximum battery life. The internal charger will boost charge to 90% of full charge, switching automatically to a trickle maintenance charge.
