intended use of the instrument.
Disclaimer
The Applent Instruments assumes no liability for the customer's failure to
comply with these requirements.
Ground
The Instrument
To avoid electric shock hazard, the instrument chassis and cabinet must be
connected to a safety earth ground by the supplied power cable with earth
blade.
DO NOT
Operate In An Explosive
Atmosphere
Do not operate the instrument in the presence of inflammable gasses or
fumes. Operation of any electrical instrument in such
an environment
constitutes a definite safety hazard.
Keep away
from live circuit
Operating personnel must not remove instrument covers. Component
replacement and internal adjustments must be made by qualified
maintenance personnel. Do not replace components with the power cable
connected. Under certain conditions, dangerous voltages may exist even
with the power cable removed. To avoid injuries, always disconnect power
and discharge circuits before touching them.
Operations not
included in the manual are
forbidden The protection measurements will be failure while beyond the scope.

Unpacking and Preparation
1.Unpacking and Preparation
&
&
&
This chapter describes:
Packing List
Power Requirements
Environmental Requirements
Cleaning
1.1 Packing List
After you receive the instrument, carry out checks during unpacking according to the following
procedures.
WARNING
If the external face of the instrument (such as the cover, front/rear panel, LCD screen, power switch, and port
connectors) appears to have been damaged during transport, do not turn on the power switch. Otherwise, you
may get an electrical shock.
Make sure that the packing box or shock-absorbing material used to package the instrument has
not been damaged.
Referring to <Packing List> in the packing box, check that all packaged items supplied with the
meter have been provided as per the specified optioned.
WARNING
If an abnormality is detected, contact the company and send the meter to your nearest Applent Instruments
sales or service office. For inspection by the transport company, save the packing box, shock-absorbing
material, and packaged items as you received them.
1.2 Power Requirement
Use AT46xx as per the following power supply conditions:
~Line: 100VAC~240VAC
Frequency: 50Hz/60Hz
WARNING
To prevent electrical shock, please connect to GND.
If users change power cord, please make sure reliable connection of GND.
1.3 Operation Environment
Ensure that the operation environment meets the following requirements.
Temperature：0°C～55°C,
Humidity ：@23°C＜70%RH

AT4610/AT4710 User’s Guide
1.4 Cleaning
To prevent electrical shock, disconnect the AT46xx/AT47xx power cable from the receptacle
before cleaning.
Use dry clothes slightly dipped in water to clean the case.
Do not attempt to clean the internal of the instrument.
WARNING
Don’t Use Organic Solvents (such as alcohol or gasoline) to clean the Instrument.
