Flashing LEDs
The two flashing LEDs represent the relative strength of the voltage and current being measured.
The green LED indicates voltage and the blue LED indicates current - - the brighter the LEDs, the
greater the relative voltage and current being measured (and visa versa). To enhance the
understanding between the circuit board and the computer display software, these are the same
colors used on the computer display software to display voltage and current.
USB Connector
The USB connector is the cube-like part on the left side of the circuit board. When a USB cable
is attached to it and to a computer, power for the circuit board is delivered from the computer and
data is transmitted by the circuit board to the computer for display and analysis.
