Technical Service Bulletin 2 – A troubling yet rare problem has been found with the PCBA 5010-4 battery analyzer as of last month and all customers are encouraged to modify their analyzer(s) themselves as per service bulletin, PCBA 5010-4 Technical Service Bulletin 2 – September 2014
Power surges or noise, on rare occasion, can cause the internal micro-controller(s) to inadvertently enter programming mode and wreak havoc within the equipment. A basic description of the problem which affects version 1 and version 2 hardware sold prior to September 2014 can be read on the Microchip support forum along my comment on the issue here, RE3 Problem
