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 available via 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.
