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.
