Condensation may occur even within the operating humidity
range. In that case, do not start using the meter until the location is
completely dry.
■ Do not place the meter in a corrosive atmosphere.
Do not install the meter 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 meter in a dusty environment.
Dirt and dust in the meter may cause electrical shock or fire.
