3. It is prohibited to access signals beyond the measurement range to the signal measure end of
the device.
4. It is prohibited to connect any connection plugs to the ground end of the front panel.
5. When disconnecting the cable, always disconnect the power supply first.
6. When the output voltage is more than 36V, attention should be paid to safety to prevent the
occurrence of electric shock accident.
7. When the device is output, no live plug and pull output signal line.
8. Before the device communicates with the PC, it should disconnect the power supply of the
device and then connect again to avoid causing damage to the device.
10. To ensure the normal operation of the installation, do not clog or seal the ventilation and cooling
system of the installation.
11. When cleaning the body, the power should be disconnected and then cleaned carefully with a
cleaner or wet cloth.
12. Do not operate the device in environment of wet or condensed water.
13. The installation shall be stored in an outer packing box after it has been used.
