Audible Overrange Alarm On/Off Button
ON: Turns on the alarm beeper.
OFF: Turns off the alarm beeper.
When ON, an audible alarm will be sounded once the voltage under test
exceeds the probe range.
Load Impedance
The output impedance of the probe is 50 . When the input impedance of
the load (e.g. oscilloscope) is
, the measured signal amplitude is
input amplitude. When the input impedance of the load is
, the
high-frequency amplitude-frequency characteristics will be flatter, and the
measured signal amplitude is half of the input amplitude.
USB Power Interface
A standard USB Type-C interface. It provides power with a standard USB
adapter. You can connect it with the oscilloscope to provide power for the
probe; or use the mobile power supply to charge for the probe. The power
specification should be DC 5 V, 1 A.
Output Interface
indicates a standard BNC output terminal, which is compatible with the
waveform measuring instruments of most manufacturers.
