LED voltage meters?
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 |

LED voltage meters?
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.

Just buy a Guest battery switch with the voltmeter built in.

My own Fluke 77 (ca. 1985) and the later models I have in the lab turn themselves
off if left on. You have to turn them off and back on to bring them back to life. They are great meters (if a bit big). That analog meter consumes enough power to be a concern if the boat is shutdown for an extended period of time. -- Chuck Tribolet http://www.almaden.ibm.com/cs/people/triblet Silicon Valley: STILL the best day job in the world.

I have a Link 10 and think its a great meter. Real handy for determining
how many amps your battery charger or alternator are putting out not to mention current draw and voltage measurement. I have heard they are on sale at Steveston Marine for $279 Cdn. You might want to call them Phone (604) 733-7031 'Course you have to buy the hookup cable which is a bit pricey......... "Steve" wrote in message ...

Steve, have a look at the RS site, http://rswww.com and do a search on
2212845. This is a 3.5 digit LED voltage meter and claims 3mA rms, there is more info on the site. I am thinking of getting these myself and I suppose could always be linked to the battery via a relay switched through the ignition circuit to prevent battery drain when the motor is not running. Cheers, Brian |

Nonsense - all you need is some generic four pair #22 or 24 cable - actually, three pair, or three separate twisted pair cables, will do, if you don't need the optional temperature sensor.

Shhh....geez, if anyone finds out I told you this the Marine Dealer Gestapo
is gonna have me shot! Drop by any Autozone store and go to the battery charger/cables display by the battery rack. There, you'll find this neat little LCD DVM with some status LEDs that swivel off the end of a cigarette lighter plug you can plug in anywhere. The LCD even has a light for night viewing. Reads out to 1/10th of a volt, which is kinda overkill but sells well. It's about $10 and requires no mounting other than a 12v Cig jack to plug it into. There's one running 24/7 in the stepvan on my desk to show the house battery conditions. It was reading 13.2V when I locked up, tonight.... But, PLEASE, don't tell Boat/US I ruined that $96 sale, ok? How can anybody sleep at night screwing a fellow boater out of a hundred dollars for some cheapassed Chinese voltmeter in a plastic case? Larry Any auto parts store should have them. I got one in every vehicle. "Steve" wrote in : I want to replace my anolog voltage meter with a LED meter that I can easily read accurately at a glance.

I believe the "scrap" in question was new, unused, cable left over from a job (I have access to similar "scrap" stainless steel too - now if I could only convince the physicists that teak would make wonderful experimental chambers....) -- Peter Bennett, VE7CEI peterbb4 (at) interchange.ubc.ca new newsgroup users info : http://vancouver-webpages.com/nnq GPS and NMEA info: http://vancouver-webpages.com/peter Vancouver Power Squadron: http://vancouver.powersquadron.ca |
