Confirm power supply
Mainland China must meet:
Voltage：AC220±10%
Frequency：50～60Hz
Prevent mutual interference via power supply
To prevent multiple devices, especially instruments and high-power equipment
from being connected to the same power grid, the pulse interference generated by
high-power equipment will cause the instrument to work abnormally or even be
damaged. It is recommended to use an AC regulated power supply to power the
instrument.
Confirm power cord
The instrument uses a three-core power cord interface, which complies with
national standards. You must confirm that the power protective ground wire is
reliably connected to the earth. Floating ground or poor grounding may cause damage
to the instrument. It is strictly prohibited to use power cord without protective ground.
Before turning on the power, make sure the power cable is in good condition and
complete. Use the power cord to connect the instrument power plug and a well-
grounded three-core power socket.
