Chapter 2. Installation and Operation
2.1 GETTING STARTED
To use the MCP39F521 Power Monitor Demonstration Board, follow the steps
described in the following sections. The meter design uses a 5A load for calibration
current and a maximum current (I
MAX
) of 15A.
It is not recommended to put more than 15A through the AC plugs mounted on the
Printed Circuit Board (PCB).
To test the calibrated meter, the following connections can be made:
2.1.1 Step 1: Wiring connections

2.1.2 Step 2: Turn on line/load power to the meter (power the meter)
The meter will turn on when the line connection is powered by 90V to 220V.
2.1.3 Step 3: Connect the USB cable to a PC with the installed
“MCP39F521 Power Monitor Utility” software
Select the appropriate COM port. If the meter is connected correctly, the connection
status in the bottom-left corner of the software will display “Meter Connected”. If no
meter is found, the status will be “Meter Disconnected”. Check that the correct COM
port was selected and try again. Press the “Start” Icon to begin showing output data and
UART transmission between the PC and the MCP39F521.
