Rugged Digital Microhmmeter for low resistance measurement,
The DO7Plus is a 10A Microhmmeter, suitable for applications within Aerospace, Utilities, Cable
or Machine Manufacturers or where a cooling curve is required to plot peak resistance. Sealed
in an IP67 case (when closed or IP53, lid open) it is ruggedly constructed to ensure durability.
The DO7Plus has a backlit LCD graphics panel, full QWERTY keyboard, temperature
compensation via optional PT100 probe, and built in coefficients for Copper and Aluminium as
well as user defined. Full cooling curve facilities are built in, with real time graphical plotting on
the LCD. Data log memory contents can be plotted and a curve fitted to calculate the peak
resistance value when t=0.
The unit has a display length of 60000 counts and auto averaging of forward and reverse
measurement removes thermal emf differences. Connectivity is improved with both USB and
RS232 for data downloading. The internal memory holds up to 1000 date and time stamped
readings and which can be viewed on the LCD or downloaded with the free software provided,
as CSV file to a PC for further analysis.
The data log memory using the latest FRAM technology which offers unlimited read/write cycles
and over 10 years of data retention, without relying on internal batteries.
The unit has built in rechargeable batteries which will provide up to 1 hour of continuous use at
10A, and up to 20 hours at all other ranges.
