This chapter describes the procedures from unpacking to installation to operation checking.
1.1 Precautions for Use
Be sure to observe the following precautions when using 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
Storage temperature range: -20 °C to +60 °C
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 contact 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.
Do not use the tester in locations near a sensitive measuring instrument or receiver.
Operation in a location subject, may cause such equipment may be affected by noise generated by the
tester.
At a test voltage exceeding 3 kV, corona discharge may be generated to produce substantial amounts of RF
broadband emissions between grips on the test leadwire. To minimize this effect, secure a sufficient
distance between alligator clips. In addition, keep the alligator clips and test leadwire away from the
surfaces of conductors (particularly sharp metal ends).
