Switches
There are only two switches to operate:
• Battery – OFF - Computer
• Select
Set it to Battery when you want to make your
measurements outside or without using a
computer, or set it to Computer when it's
plugged into your computer using the supplied
USB cable. And set it to OFF when it's not in
use.
Push the Select button to cycle through the
four main LCD screens. You can even hold
the Select button to "freeze" the display if the
numbers are changing too fast.

USB Connection

A USB "type B" connector on the back of the unit
allows connection to a Windows PC computer
(MAC computers are not supported at this time).
Power for the Renewable Energy Monitor is
supplied by the PC via the USB cable.

Units of Measurements
The Renewable Energy Monitor measures
standard electrical units like voltage, current,
power, energy and resistance. It also
measures the RPM speed of the WindPitch
wind turbine.
Voltage is measured in volts or millivolts
(mV). A millivolts is 1/1000 of a volt but when
seen on the LCD screen it can provide a
more accurate measure of the voltage. For
example...
1.23 volts = 1230 mV
10.456 volts = 10456 mV
Current is measured in amps or milliamps
(mA). A milliamp is 1/1000 of an amp. For
example...
0.003 amps = 3 mA
1.256 amps = 1256 mA
Power is measured in watts or milliwatts
(mW). A milliwatt is 1/1000 of a watt. For
example...
0.034 watts = 34 mW
2.987 watts = 2987 mW
Energy is measured in Joules. Energy is
basically power x time and one Joule is equal
to one watt-second. For example.
21 Joules = 21 watt-seconds or the amount of
power used in 21 seconds.
RPM is a measure of the rotational speed
of the wind turbines blades. RPM is used
in experiments to show how the above
parameters are affected by higher or lower
RPM rates.
