Dear all,
I have had a bad experience. :palm:
Today It is some kind of “damage control”
2 days ago a water pipe burst in my house and of course spray water ower my new developed electronic lab (note my amateur lab).
I awaited 2 days before power up my gear.
My old FLUKE 79iii was not working correct. It was flicking around in the different UIR modes.
My new purchase HAKKO FX-888D was making some disturbing noise that remind me kind of sparks noise. I think it is busted!
My new RIGOL DS1054X seemed to work.
My new SIGLENT SDM3065X seemed to work also.
My biggest concern is the expensive RIGOL and SIGLENT if there are OK or not.
During their boot sequinse they are not making any error code!
So my big Q should I be nervous?
Please advise
capt bullshot:
Open up the stuff and dry them carefully. Remove batteries immediately if water gets inside electronic stuff.
As long as there's no power applied, water doesn't cause much damage to the electronics.
Powering on while there is still moisture inside can easily ruin the equipment.
Gyro:
Two days isn't nearly enough time for water that has been sprayed over (and into) equipment to evaporate of its own accord.
You shouldn't have powered up anything without checking for water ingress first! I suggest you don't power anything else up before you have taken the covers off and checking for signs of water.
Even if something apparently powers up ok, tap water on device pins etc. will cause electrolysis and corrosion. I suggest you check things that you already powered up too.
You should also remove batteries from portable equipment that gets wet immediately!
TheNewLab:
excellent advise. Bob Pease once called Tektronix about cleaning a test equipment PCB in the shower. They replied they have an old dishwasher that they stick their boards into when they get a return or do service on a customers unit.
Key, is drying out, and removing any contaminants, "yucky" stuff from the water. If yucky stuff just use some board cleaner or wash...or 99% alcohol
Try putting next to a heater or central heating outlet. Around 100ºF to 150ºF (tek uses 200ºF) with plastics that will help dry out..

They missed to tell other "simple" things: old dishwasher is fed with deionised water that comes out of reverse osmosis filtration system. Then for sure they have ultrasonic and alcohol baths for "final rinse" and quick dry.
[edit] If Tektronix wash PCB's in tap water - I will never ever buy any piece of equipment from them ;)
