2-1/2” Inch Panel Meter: 0-20V & 0-1A Scales: 1mA Movement: Very Nice Meter For Sale -

1mA Movement Very Nice MeterDescription:Hereis a real nice panel meter that can be used for many projects.
Of course itwould be especially suited for a power supply with the given scale reading.
The meter scale reads 0-20 Volts and 0-1 Amps(See Photos).
In fact these were purchased from a manufacturer of power supplies
who had alarge overstock of these meters. You can also ignore the scale and use it as a power meter.
It would be a nicepower meter for a QRP rig. Top scale could be
0-20 Watts and bottom scale couldbe 0-1 Watts, etc.The meter face is easily removable and you could turn around
the meter faceplate and make your own meter face.It has a meter movement of 1mA. (1mA current will cause a full
scale movement.You will need shunt resistors. If you are not familiar
with shunt resistors,you will have to look it up. It is not difficult).Meter measures 2-1/2” Wide x 2.36” High.
Overall depth is about 1.34”

I do not have a template for the cutout to mount the meter.
You will have to drill a 2” diameter hole then four small holes
for the metermounting screws. What I do on my projects is
first make a template withordinary paper. Cut a 2” diameter
hole in the paper. Then pass the meterthrough it pressing
hard so the four screws also pass through the paper.
Ofcourse, you could also use calipers and just measure precisely.
There is some leewayafter the 2” hole is cut.
The square part of the meter will cover the hole.
You will need a drill and some files to mount this meter.
Look at the photos to get an idea.
