9.Notice
●When dual channels are used simultaneously, the ground clamps of the two
probes must be connected together. It is strictly prohibited to connect the
ground clamps of the two probes to different potentials, especially at
different potential terminals or 220V of high-power equipment. Otherwise,
the oscilloscope motherboard will be burned because the two channels are
grounded together, and connecting to different potentials will cause a short
circuit in the internal ground wires of the motherboard, as is the case with all
oscilloscopes.
●The maximum tolerance for the BNC input of the oscilloscope is 400V, and it is
strictly prohibited to input voltage exceeding 400V under the 1X probe switch
●When charging, a separate charging head must be used. It is strictly prohibited
to use the power supply or USB of other currently tested devices, otherwise it
may cause a short circuit to the motherboard ground wire and burn the
motherboard during the testing process.
●Before using the product, please check if the insulation near the shell and
interface is damaged
●Please hold your finger behind the protective device of the pen
●When measuring the circuit to be tested, do not touch all input ports
●Please disconnect the test probe and circuit connection before changing the
gear position
●When the DC voltage to be tested is higher than 36V and the AC voltage is
higher than 25V, users should take precautions to avoid electric shock
●When the battery level is too low, a pop-up prompt will appear, please charge
it in a timely manner to avoid affecting the measurement performance
