It is of rugged construction 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 mean 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
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.
