Digital Amp Meter
Finanly
A affordable digital amp gauge that works on 12 VDC
with a isolated power supply.
Now
you can keep an eye on the current level of your booster
without running large wire into the passenger compartment
This
digital panel meter comes with a hundred amp shunt
and once calibrated can be accurate within one amp
You
will love the cool green display that looks great
when mounted in a small plastic box or in the dashboard
The
shunt is a heavy duty 100 amp shunt with very low
power loss and comes with 2 large 14 mm nuts.
We
recommend this shunt up to 100 amps with direct current
or 75-80 amps with a PWM

Use
the Range adjuster to calibrate your meter.
This adjuster is fragile so be carful not to turn
it to hard if you do it could break and is not covered
by our 30 day warranty. A regular phillips head screwdriver
fits just fine and if you go out of range the meter
will stop working so just move it back to where it
was befor and the meter should be working agin.
It is best use a traditional amp gauge to help you
calibrate your digital amp gauge. To do this connect
your analog amp gauge to the + wire to you cell, turn
the cell on and set the digital gage to read the same
as th analog gauge.
A
handheld VOM works fine for this also but will give
you a slightly lower reading because of the voltage
drop across the wire and the meter. Most handheld
meters are only rated for 1 min at 20 amps so be carful
not to leave them connected for very long.
Installation
instructions:
The
red and black wires connect to a switch power source
(ignition switch)
The Green and Blue wires connect across the shunt
and can be connected either way but it seems to be
more accurate with the blue wire connected to the
negative side.
The
Shunt can be connected to either to the + or - side
but we recommend conecting the shunt to the ground
side of your system.
Face
plate:
Cut
a rectangular hole slightly larger than the faceplate
.91" x 1.65"
Remove
the meter from the black mounting flange and install
the black mounting flange in the hole you have made.
Push
the meter into the black mounting flange from the
back until it snaps into place, reconnect the plug.
