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).
