Float Measurement Safety
The instrument can be used to measure floating signal when using
battery power. Grounding terminals of the two channels should be
connected to the same reference voltage while measuring
dual-channel floating signal. To avoid hazards that may happen
during measurement, please read the following notices carefully.
Warning
Floating signal can not be higher than 30Vrms or 42Vpk.
Warning
To protect the instrument and other products connected to it, do
not connect it to grounding equipment (such as computer or
printer) through a USB cable while measuring floating signal.
