Instrument Installation
• This instrument is not drip-proof. Install the instrument with the
measurement cables hanging lower than the instrument to pre-
vent water or other fluid from entering the instrument through the
measurement cables and terminal block.
• The maximum operating (ambient) temperature for the LR8432-
20 is 40°C. Do not attempt to use in higher temperature environ-
ments.
• Correct measurement may be impossible in the presence of
strong magnetic fields, such as near transformers and high-cur-
rent conductors, or in the presence of strong electromagnetic
fields such as near radio transmitters.
• If liquid enters the enclosure through an air vent or other opening, it
may damage the instrument’s internal circuitry. Exercise caution con-
cerning the surrounding environment when installing the instrument.
Do not place the instrument on an unstable table or an inclined
place. Dropping or knocking down the instrument can cause injury
or damage to the instrument.
