Help needed with Hanna Potentiometer PCB
« on: April 01, 2019, 06:13:19 am »
Hi everyone!

I’m a newbee here and I already got help and repaired my WR3M Weller Soldering Station.

I’m on a new peoject. I’ve got a Hanna Potentiometer (aka pH meter) but despite of looking good, it has never worked, not even turned on.

It runs in 12VDC. If i check the input, the Voltage does get to the PCB. The tesistance across the Fuse is <2Ohm.

I’ve got no clue of where to start. [emoji29]
