RESISTANCE MEASURING INSTRUMENTS D07 RUGGED DIGITAL MICRO OHMMETER FOR LOW RESISTANCE MEASUREMENT The DO7 is a practical instrument for low resistance measurement, ideal for use in the workshop, field or test facilities. key feature DO7 True 4 terminal measurement eliminates lead resistance errors ■ 10 Amp measuring current ■ Rechargeable batteries with built-in charger ■ Measuring range 600 micro ohm...60 ohm ■ Resolution 0.1 micro ohm on 600 micro ohm range ■ 0.8" LED display daylight viewable ■ Auto average of forward and reverse measurement ■ charger will boost charge to 90% of full charge, switching Remote start socket ■ automatically to a trickle maintenance charge. Warning LEDs All solid state design ■ illuminate when an open circuit lead condition is detected. A front Wide range of leads and accessories available ■ panel socket provides a serial RS232 output for connection to an RS232 printer output ■ 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.
