As the title say, has anyone idea of the problem
I opened the battery cap for battery check
after reassembling display dont switch off
Have you checked the switches? I had this happen once - one of the switches snapped - looked OK from the outside but the display thoguht I had it permanently held in. Remove the circlips and the switches pop out - all very simple. I think it's the top switch (the bottom dow the mV reading, althgouth that's from memory). I swapped them over whilst waiting for a replacement. Hope that makes sense!Rich
