I picked up a MDTECHPLUS Digital Meter at a garage sales. It looked new and only cost 10.00, the owner said he knew nothing on how it worked but it probably needed a new battery. I put a new battery in it and all it would do is: the backlight would come on for about 10 seconds and then nothing, about 1 out of ten times the battery indicator would show.
So far I have:
• Disassembled the unit
• Clean both sides of the broad with alcohol
• Looked for any cold solder joints
• Cleaned the dial connects
• And yes tried a new battery
I really like to get this unit working because it has an RS232 interface with it which would help me a lot.
Any ideas on what to try next would be appreciated.
Thanks in advance.
