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 dir
ected airflow such as from an electric fan or air conditioner
vent. Thermocouple inputs are prone to measurement errors.
• When the instrument is moved to a location with significantly dif-
ferent ambient temperature, allow at least 30 minutes for thermal
equalization be
fore measuring.
• Correct measurement may be impossible in the presence of strong
magnetic fields, such as near transformers and high-current conduc
-
tors, or in the presence of strong electromagnetic fields such as near
radio t
ransmitters.
• 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.
