Hi Mark,

I recently purchased a digital volt meter which is self powered and has a large clear LED display. It's reading is bang on with an expensive "Fluke" meter I borrowed. The unit draws a miniscule current and gives me an accurate and constant voltage reading. I have mounted it in a cupboard so I am not constantly looking at it worrying about my batteries state of charge. :D

Cheers Chris

That sounds good, Chris.
Obviously mine draws more than your "miniscule" amount, flattening its battery over (I think) no more than 36 hours.
But I HAVe wired mine up to a 12V plug, so I juat have to plug it in to read the voltage (AND remember to turn it off again :roll: )

Hi Mark,

I have just re read my post and I should probably clarify that my meter is powered by the 12v source that it is actually measuring. No need to worry about flat batteries.

Cheers Chris

Sounds ideal. Does that type of meter have a name? Where did you get it? (Was it expensive?)

Hi Mark,

I found it on trade me and I think I paid around $75.00 for it. I have just checked the details of the trader shaynedw and he has no current listings but his email address is shaynedw@slingshot.co.nz

The auction number of my purchase is 246984260 This should enable you to check the details of the unit.

Cheers Chris

Thanks for digging that out for me Chris.
It's a bit late for me to do anything about it for this trip but I may need to follow it up if I find it impossible to go 10 weeks without remembering to turn the thing off every time I use it :shock:

Hi Mark,
You could always just fit a panel voltmeter and leave it on all the time. Cost is approx. $22 at Jaycar. Add a few dollars if you want to mount it in a small plastic box.

:idea: or maybe a press and hold switch. Sounds like something to do before next trip (if this voltage thing seems precise enough for my purposes.
