Re: Fluke 187 corroded battery terminals - how to clean?

Baking soda is for acid batteries. Duracell Procells are alkaline batteries. Baking soda is not of use.

if it's dried already, it shouldn't be of electrical concern, see my post above.

emery cloth an a small screw driver, the baking soda vinegar neutralized it, can clean it with the emery an a small screw diver.

The meter should be ok, electrolyte is only conductive as a liquid (not a crystallized salt). As for the batteries, who knows... I'd try the meter with some fresh alakalines before I risked some NiMHs on it.

Also posted on eevblog where most of the multimeter people hang out, but I want to get more opinions and suggestions from people here.

I bought this used Fluke 187 off ebay. Opening up the battery compartment reveals some past battery leakage/corrosion. The supplied batteries are not leaking and are Duracell Procell with expiry date 2017.

I have read about using baking soda and vinegar to neutralize the corrosion as per

http://www.eevblog.com/forum/beginne...ked-batteries/

So I applied the mix using a q-tip, but as you can see, there is still corrosion (the two middle cell holders)? Is it just a matter of applying more of the mix over and over again? Ideally, I would like to "soak" the entire back case overnight, but I'm afraid of damaging or staining the case.

I don't *think* the main pcb was affected by the corrosion due to the design of the back plastic casing. I can't detect any corrison on the main board. All the rotary functions seem to work correctly.

I want to make sure there are no long term problems as I expect this multimeter to last a long time. I will be using nimh batteries for this Fluke 187.

Suggestions are welcome.
