Precautions for Installation
Be sure to observe the following precautions when installing the tester.
■
Do not use the tester in a flammable atmosphere.
To prevent explosion or fire, do not use the tester near alcohol, thinner, or other
combustible materials, or in an atmosphere containing such vapors.
■
Avoid locations where the tester is exposed to high
temperatures or direct sunlight.
Do not locate the tester near a heater or in areas subject to drastic temperature
changes.
Operating temperature range: +5 °C to +35 °C (+41 °F to +95 °F)
Storage temperature range:
-20 °C to +70 °C (-4 °F to +158 °F)
■
Avoid humid environments.
Do not locate the tester in a high-humidity environment—near a boiler, humidifier,
or water supply.
Operating humidity range:
20 % to 80 % rh
(no dew condensation permitted)
Storage humidity range:
90 % rh or less
(no dew condensation permitted)
Condensation may occur even within the operating humidity range. In that case, do
not start using the tester until the location is completely dry.
■
Do not place the tester in a corrosive atmosphere.
Do not install the tester in a corrosive atmosphere or one containing sulfuric acid
mist or the like. This may cause corrosion of various conductors and imperfect con-
tact with connectors, leading to malfunction and failure, or in the worst case, a fire.
■
Do not locate the tester in a dusty environment.
Dirt and dust in the tester may cause electrical shock or fire.
■
Do not use the tester where ventilation is poor.
This tester features a forced-air cooling system. Provide sufficient space for the air
inlet on the lateral side and the air outlet on the rear side to allow air to flow.
■
Do not place the tester on a tilted surface or in a location
subject to vibrations.
If placed on a non-level surface or in a location subject to vibration, the tester may
fall, resulting in damage and injury.
■
Do not use the tester in locations affected by strong magnetic
or electric fields.
Operation in a location subject to magnetic or electric fields may cause the tester to
malfunction, resulting in electrical shock or fire.
