Safety Requirement
General Safety Summary
Please review the following safety precautions carefully before putting the
instrument into operation so as to avoid any personal injury or damage to the
instrument and any product connected to it. To prevent potential hazards,
please follow the instructions specified in this manual to use the instrument
properly.
Use Proper Power Cord
Only the exclusive power cord designed for the instrument and authorized for
use within the local country could be used.
Connect the Probe Correctly
If a probe is used, do not connect the ground lead to high voltage since it has
isobaric potential as the ground.
Observe All Terminal Ratings
To avoid fire or shock hazard, observe all ratings and markers on the
instrument and check your manual for more information about ratings before
connecting the instrument.
Use Proper Over-voltage Protection
Ensure that no over-voltage (such as that caused by a bolt of lightning) can
reach the product. Otherwise, the operator might be exposed to the danger of
an electric shock.
Do Not Operate Without Covers
Do not operate the instrument with covers or panels removed.
Do Not Insert Anything Into the Air Outlet
Do not insert anything into the air outlet to avoid damage to the instrument.
Avoid Circuit or Wire Exposure
Do not touch exposed junctions and components when the unit is powered on.
Do Not Operate With Suspected Failures
If you suspect that any damage may occur to the instrument, have it inspected
by JUNTEK authorized personnel before further operations. Any maintenance,
adjustment or replacement especially to circuits or accessories must be
performed by JUNTEK authorized personnel.

III
Provide Adequate Ventilation
Inadequate ventilation may cause an increase of temperature in the instrument,
which would cause damage to the instrument. So please keep the instrument
well ventilated and inspect the air outlet and the fan regularly.
Do Not Operate in Wet Conditions
To avoid short circuit inside the instrument or electric shock, never operate the
instrument in a humid environment.
Do Not Operate in an Explosive Atmosphere
To avoid personal injuries or damage to the instrument, never operate the
instrument in an explosive atmosphere.
Keep Instrument Surfaces Clean and Dry
To avoid dust or moisture from affecting the performance of the instrument,
keep the surfaces of the instrument clean and dry.
Prevent Electrostatic Impact
Operate the instrument in an electrostatic discharge protective environment to
avoid damage induced by static discharges. Always ground both the internal
and external conductors of cables to release static before making connections.
Handle with Caution
Please handle with care during transportation to avoid damage to keys, knobs,
interfaces, and other parts on the panels.
Notices
1.Make sure that the input power is correct.
2.The shell of the instrument is fragile and easy to corrode. Please don't hit or
close to chemicals to avoid corrosion.
3.Working temperature: 10~ 50℃, storage temperature : 20 ~70℃, and keep
the instrument in a dry environment.
4.Do not attempt to disassemble the instrument， it will void the warranty. There
are no user-serviceable parts inside the instrument. Repairs can only be made
through designated repair outlets or sent back to the factory.
5.Please avoid placing unsafe items such as lighted candles, cups with water,
and corrosive chemicals on the surface of the instrument to avoid damage to
the instrument.
6.The display screen is a fragile device, please do not touch or bump it .
Please avoid children playing with the instrument. When there is dirt on the
LCD surface, wipe it carefully with a soft cloth.
7.Please do not move the instrument violently to avoid causing irreparable
damage to the internal circuit. If the instrument does not work properly, please
contact the supplier!
