Cell voltage

Saga · 1st December 2006, 19:24

Hi,

Does anybody know the reason why if it's necessary to use an adapter to check out the cell voltage ?

What damage can be caused by not using it ?

Thanks for your help.

Cheers,

Eveline

Hi Eveline,

What do you mean by "necessary to use an adapter"?
What kind of adapter do you think of?

Just use a multimeter and that's it! (if you don't disconnect the cell)

On the newer vision cells it comes with an adapter that you fit to the cell & then put the probes of the meter onto the adapter plug .This prevents it shorting across the terminals if you slip with the probe .that is as I understand it from my instructor .

Ah, OK, I just forgot that the Vision/Evo has a different connector.

Thank you.

It Depends On The Type Of Sensor You Are Trying To Test. Some Sensors You Can Access The Pins Very Easily Others You Can't.

the old classic cells were easy to do (3 seperate pins ) but the new vision/evo cells (APD10) are fiddlier

I just put my multi-meter prods in gently.

Admittedly the only thing I ever discovered that was used by divers but was still diver-proof was the Combro Stainless Steel backplate. We even tried driving the company van over one and it just made dints in our car park. SMB connectors have a nice petite center pin and ham fisted Harry will bend that in no time and then refit the plug with his port-hole removing lump hammer and wonder why it doesn't work anymore.

Probably to prevent the centre pin of the cell being bent or broken by insertion of a probe.....

Still not very clear what damage can be caused to the cell

I can't imagine that there would be any electrical damage, especially for short duration short circuit. It would only be mechanical damage or ease of access to the connectors.
