Cropico D07 10 Amp , low resistance
measurement
Digital
Micro-Ohmmeter
The DO7 is a practical
instrument for low resistance measurement, ideal for 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 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, and 20 hours on all others.
Battery charge indicators are provided. 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.
The DO7 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.
