Fluke 725 repair
« on: June 19, 2018, 07:15:28 am »

i Just got a Fluke 725 it in good physical condition, but unable to soures mA, in the display it just says OL, and nothing comes out of the terminals. I have check the fuses and all are okay, And nothing looks burned inside, I notes that there are some relays and the connected runs to the mA terminals and have not checked them, donĀ“t if it could be them ? 

Does any of you have a schematic,or know what to look for ?

I'd be surprised if a 725 could be easily repaired given all the miniaturisation inside one, but someone may be able to.

What are you trying to drive in mA source? I'm assuming you know that what you're driving is working ok?

Is the Ol flashing?

Which fuses did you check? That sounds familiar to one of the issues I had with a 725 and it ended up being a blown fuse. One of the odd looking 2 pin push in fuses
