Chapter 1 Important Notes
The following safety measures must be observed during all phases of operation,
maintenance, and servicing of this instrument. Failure to observe these measures or the
warnings and precautions indicated in this manual will likely affect the basic protection
provided by the instrument. Also, this can undermine the safety standards for which the
instrument was designedandmanufacturedandtheintendedscopeofuseoftheinstrument.
1.1
Instrument grounding
To ensure the personal safety of the operator, please use three-prong grounding plug
provided by the manufacturer. When using the adapter, please use a grounding socket that
matches the plug to ensure that the input power line of the instrument is reliably grounded.
1) Use of power supply
Before the instrument adapter is connected to the power cord, it must be ensured that
the ACpower supplyvoltage (100to 240VAC) andfrequency (50/60Hz) are consistent with
those required by the instrument adapter. When making the power cord connection, make
sure that the instrument power switch is off. Do not touch the power switch and power cord
with wet hands. It is prohibited to disconnect the power cord when the instrument is not
powered off. It is forbidden to touch the power cord to the hot surface of the instrument. Do
not clean the instrument when it is not disconnected. Please turn off the power when the
instrument is no longer in use.
2) Power cord
The instrument should normally use the power cord supplied with it. If the power cord
is broken, it must be replaced without repair. When replacing the power cord, it must be
replaced with the same type of power cord of the same specifications. When this instrument
is in use, do not place anything on the power cord, and do not place the power cord in a
place where people move around.
3) Power cord plugging and unplugging
Power cord plugging and unplugging must be the correct handheld plug operating parts,
plug insertion should ensure that the plug is completely, tightly inserted into the socket, do
not pull hard when pulling out the plug, or yank the power cord.
1.2
Placement of the Instrument
1) The instrument should not be placed in a location where it is difficult to disconnect the
power supply.
2) The instrument uses semiconductor cooling and fan-assisted heat dissipation, so when
placing the instrument, ensure that there is no obstacle within 15cm around the
instrument, and when multiple instruments are used at the same time, the distance
between each instrument should be not less than 30 cm.
