While trying to repair a Datron multimeter, my good old Philips PM2527 multimeter started to fail… grrreat timing.
Yes, it's an old meter, but I like it.
Symptoms: DC Volt in automatic range showed eg. 10V (correct), manual mode showed ~4,98V (wrong, always about 50%). Also, the decimal point jumped around. After switching ranges and modes around the DC volt mode is often completely out of order, all I see is a "00", which is out of range.
But: If I power off and power on again, it may work again without a problem - or may not. Ohms seem to work fine, but I haven't tested this in deep.
Anyone seen this before? The unit was never serviced, so prob. a recap? The service manual lists ~26 electrolytics, but I haven't look inside yet.
