Panel volt meter

I just found a really nice panel volt meter. It is
7/8' X 1-3/4' X 1/8'. Weighs nothing. It needs a
single 7/32' hole for mounting. The wires run through
the single hollow mounting stud to the rear of the
panel. Really slick! 2 wires (+V & ground). Reads
4V to 25V. It's from Lascar Electronics. Model #
EMV-1200. Cost is $25.00

They also have a hobbs (hour) meter. Same size & price.
Reads either total time or trip time. Could be useful
for keeping track of flight times.

I have that exact panel voltmeter on my panel in my Glider. It is great to
know how the battery is doing as the hours tick by, as well as part of the
preflight/pre-takeoff check. You can also see how deep the battery drops
when you transmit on the radio. Well worth putting one in.

Had one in my panel for a few years now. Also available from Allied
Electronics at www.alliedelec.com. Just search for EMV 1200.

I have it a little placard to sort of indicate remaining capacity. 100% =
12.7V, 75% = 12.4V, 50% = 12.2V, 25% = 12.0V, 11.9V = 11.9V.

Wow that is a very nice item. Small, each mounting and wiring, and LCD
so very visible under bright light conditions. For those in the US,
the Lascar site is in the UK. There are several US companies that
stock the item such as http://www.alliedelec.com. Search for
"EMV1200". Note that there is also a "EMV1200-40" which is more
expensive and goes up to 40VDC. The EMV1200 only goes to 20VDC which
is fine by me. Thanks for puttting me onto this item.

Another comment. The EMV1200 goes to 25VDC. It also only draws 3ma
which means that it can safely be on all the time. My Cabridge 302 can
display battery voltage also but it is 1) a little difficult to get to
when flying and 2) I'd rather have a dedicated display. Thanks Again.

I installed one of those EMV-1200 units a few years ago when I flew my
first GPS (that is, non-photo) contest. I'd read about it here on RAS
and ordered it from Allied.

It went in really easy (I just pegged the wires down under the
appropriate screws on the panel terminal strip), works good, and looks
good. I'll get another for my next glider.

3 ma is 1 amphour after only two weeks, or 15% of the typical 7 amphour
battery. I suggest it be wired in after the master switch instead of
left on all the time. If you routinely remove your battery when you
aren't flying, then the drain isn't a probem.

I received the Lascar EMV 1200 meter and like it alot. Small but not
too small, easy to mount, LCD so good in direct sunlight,
"splashproof". Very nice indeed.

Note that there is an analog version of the meter with the same
footprint, the EMA 1710. It can also be a ammeter. Only $20.

It can be set up to monitor most any voltage or current by adding a
simple two resistor "bridge". If anyone is interested in knowing how
to do this, drop me an email.

If you have a Colibri it will also give you the voltage readout .

I have found the there is also an analog version of the same meter for
about $20. It is the EMA1710. Same mounting arrangement. Might be a
little easier to read. A few differences in use though.

1) The meter is only 0-1vdc so you have to add a two resistor bridge to
scale the input range you need. The instructions tell you how.
2) There is no scale on the meter, just red/green markings.
3) There are three wires. Ground, a +5 to +12vdc supply to power the
meter and a sense line.

The meter can also be wired to read current by using it to measure the
voltage across a fixed 1% resistor. E=IR comprende?
Finally they have a
