6.1 Outputting Waveform and Resultant

RMS Values

Do not simultaneously connect the USB and output terminals of the
tester to external devices.
If the ground potential of the device connected to the USB terminal
differ from that of the device connected to the output terminal, a
short circuit current could flow via the FT3470-50 and damage the
device connected to the USB terminal by fire.

When both terminals need to be used to connect, for example, a PC
to the USB terminal and an oscilloscope to the output terminal,
make sure that both devices are connected to ground or use a
device (for example, a recorder) with insulated input terminals on
the output terminal side.

Never connect the tester as shown in the figure.
