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.
NOTE
If an abnormality is detected, contact the company and transport 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 Setting up Fuse
~Line: 110VAC/220VAC, 50Hz/60Hz
Fuse: 250V 1A Slow Blow
Please use the following fuse type.

When you need a fuse, contact your nearest Applent Instruments sales or service office.
To verify and replace the fuse, remove the power cable and pull out the fuse holder.
1.3 Environmental Requirements
Set up the AT5108/AT5110/AT5120 where the following environmental requirements
are satisfied.
Operating Environments
Ensure that the operating environment meets the following requirements.
Temperature: 0C to 55C

9
Unpacking and Preparation
Temperature range at calibration: 23C±5C (<1C deviation from the temperature
when performing calibration)
Humidity: 15% to 85% at wet bulb temperature ≤40 °C (non-condensation)
Altitude: 0 to 2,000m
Vibration: Max. 0.5 G, 5 Hz to 500 Hz
1.4 Cleaning
To prevent electrical shock, disconnect the AT5108/AT5110/AT5120 power cable from
the receptacle before cleaning.
