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
