Installation Precautions
• If the instrument is used in any state other than the following, the
measurement accuracy may not satisfy the device specifications.
• Leave sufficient space around the ventilation holes and install the
instrument with the holes unobstructed.
• Avoid temperature changes around the terminal block. Especially
avoid directed airflow such as from an electric fan or air conditioner
vent.Thermocouple inputs are prone to measurement errors.
• When the HiLogger is moved to a location with significantly dif-
ferent ambient temperature, allow at least 30 minutes for thermal
equalization before measuring.
• 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.

Handling the Instrument
• Do not allow the instrument to get wet, and do not take mea-
surements with wet hands. This may cause an electric shock.
• Do not attempt to modify, disassemble or repair the instru-
ment; as fire, electric shock and injury could result.
To avoid damage to the instrument, protect it from physical shock
when transporting and handling. Be especially careful to avoid
physical shock from dropping.
This instrument may cause interference if used in residential
areas. Such use must be avoided unless the user takes special
measures to reduce electromagnetic emissions to prevent interfer-
ence to the reception of radio and television broadcasts.
