Operation Instructions
•
Faraday Setup
:
Faraday
is designed as a pocket power meter to measure Voltage, Current and Power going through
any of the 4 channels. Below are the four setup configurations can be used:
•
Channel 1&2 (60V 25A):
1.
Connect Power Source and Device Under Test (DUT) in series to Channel 1 (or 2) to
measure Voltage, Current and Power as shown in
Figure 1
2.
Connect Channel 1 for the input and Channel 2 for the output as shown in
Figure 2
to measure DC power supply efficiency;
•
Channel 3 (20V 2A)
3.
Connect an USB Type C source to the CH3_IN connector and an USB Type C device
to the CH3_OUT connector to measure Voltage, Current and Power of an USB Type
C device as shown in
Figure 3
•
Channel 4 (5V 300mA)
4.
Connect an USB device on the channel 4 USB-A connector to measure Voltage,
Current and Power of an USB device as shown in
Figure 4
•
Board Operation
:
o
Select one of the test setups as shown above and connect the power and device
o
Connect the Faraday board to a PC using USB port (J1) using the USB cable provided, the board
will enumerate as Serial COM Port
o
Press the CHx button corresponding to the desired channel number (i.e. CH1, CH2 etc) on the
bottom right corner of the Faraday board to view measurement information on the LCD display
o
Press buttons CH1 and CH2 together at the same time, power and efficiency information of the
channels 1&2 will be shown on the LCD display
•
PC Terminal Connection (Optional)
Connect to the Serial COM Port (115200, N, 8, 1; enable local echo)
o
Right after startup, press enter or type help and then press enter to view basic commands
o
After a command is entered, pressing enter again will repeat the last command
o
Type “getall” to view all channels
o
Enter commands such as “getall, getchx, getvx, getix, geteff12”, where x is the desired
channel number
