direct sunlight, high temperature or humidity, or condensation. Under
such conditions, the instrument may be damaged and insulation may
deteriorate so that it no longer meets specifications.
• This instrument should be installed and operated indoors only,
between 10 and 40°C, 80% RH or less, and at an altitude of 2000 m
or less, and also stored in a range of temperature and humidity from
-10°C to 55°C, 80% RH or less.
• This instrument is not designed to be entirely water- or dust-proof. To
avoid damage, do not use it in a wet or dusty environment.
• Do not use the instrument near a device that generates a strong
electromagnetic field or electrostatic charge, as these may cause
