2 Important Safety Information
This manual contains information and warnings that must be followed by the user for safe operation
and to keep the product in a safe condition.
2.1 General Safety Summary
Carefully read the following safety precautions to avoid personal injury and prevent damage to the
instrument and any products connected to it. To avoid potential hazards, please use the instrument
as specified.
To Avoid Fire or Personal Injure.
Use Proper Power Line.
Use only the special power line approved by the state and local authorities.
Ground the Instrument.
The instrument grounds through the protective terra conductor of the power line. To avoid electric
shock, the ground conductor must be connected to the earth. Make sure the instrument is grounded
correctly before connecting its input or output terminals.
Connect the Signal Wire Correctly.
The potential of thesignal wireis equal tothe earth, so donot connect the signal wire to a high voltage.
Do not touch the exposed contacts or components.
Look over All Terminals Ratings.
To avoid fire or electric shock, please look over all ratings and signed instructions of the instrument.
Before connecting the instrument, please read the manual carefully to gain more information about
the ratings.
Equipment Maintenance and Service.
In the event of an device failure, please do not dismantle the machine for maintenance. The device
contains capacitors, power supply, transformers and other energy storage devices which may cause
high voltage damage. The internal devices of the device are sensitive to static electricity and direct
contact can easily cause irreparable damage to the device. It is necessary to return to the factory or

tothecompany'sdesignatedmaintenanceorganization for maintenance.Be suretopulloutthepower
cord before repairing the device. Live line operation is strictly prohibited. The device can only be
powered on when the maintenance is completed and the maintenance is confirmed to be successful.
Identification of Normal State of Equipment.
After the device is started, there will be no alarm information and error information at the interface
under normal conditions. The curve of the interface will scan from left to right freely; if there is a button,
alarm or error prompt, the device may be in an abnormal state. You need to view the specific prompt
information. You can try to restart the setting. If the fault information is still in place, do not use it for
testing. Contact the manufacturer or the maintenance department designated by the manufacturer to
carry out maintenance to avoid the wrong test data caused by the use of the fault or endanger the
personal safety.
Do Not Operate with Suspected Failures.
If you suspect that thereis damage to the instrument, please let only qualified service personnel check
it.
Avoid Exposed Circuits, Wire, or Components.
Do not touch exposed contacts or components when the power is on.
Do not operate in wet/damp conditions.
Do not operate in an explosive atmosphere.
Keep the surface of the instrument clean and dry.
Only lithium batteries with the same specification could be used to replace the battery on the
main-board.
The responsible body or operator should refer to the instruction manual to preserve the
protection afforded by the device. If the device is used in a manner not specified by the
manufacturer, the protection provided by the device may be impaired.
Any parts of the device and its accessories are not allowed to be changed or replaced, other
than authorized by the manufacturer or agent.
