The meter itself doesn't usually draw much power, just a few mils. But
if it is an actual LED meter the the LEDs are generally pretty large and do draw a fair amount. LCD meters are pretty low current and it is the backlighting that draws most of the power. A better solution is an energy monitor link the Link 10 or eMeter. It is made to draw little power and the display goes blank to save power after a minute of so. Also monitors currrent, amp-hours, etc. The one I have (Ample Power ESP) hardly draws anything and I leave it on all the time. Actually no way to turn it off. Goes into a low power mode automatically. Doug s/v Callista "Steve" wrote in message ... I want to replace my anolog voltage meter with a LED meter that I can easily read accurately at a glance. I see them in the catalogs but don't notice any spec on the amount of current they draw if I leave it on all or most of the time. The way my power panel is set up (OEM), you have to push a momentary switch to activate the anolog meter.. I never considered that this meter would draw enough current to be of concern. Presently, for accurate digital volt readings, I use my Fluke muli-meter but if I leave that hooked up the 9 volt battery will run down. Any thoughts?? Steve s/v Good Intentions |
