2.1 Where and How to Install
Location
Install the MV indoors in an environment that meets the following conditions:
• Temperatureof0to40°C
Install the MV in a location where the temperature is 0 to 40°C, and the humidity is 20
to 80% RH (5 to 40°C). Only use the MV when there is no condensation on it.
Note
Condensation may form when moving the MV from a low temperature/humidity environment to
a high temperature/humidity environment, or when there is a sudden change in temperature.
Temperature/humidity changes may also result in thermocouple measurement errors. In these
kinds of circumstances, wait for at least an hour before using the MV, to acclimate it to the
surrounding environment.
• Altitudeof2,000morbelow
• Goodventilation
To prevent overheating, install the MV in a well-ventilated area. We recommend that
you leave 50 mm or more of space around the top, left, and right of the MV.
• Notmuchmechanicalvibration
Install the MV in a location without much mechanical vibration. Placing the MV in a
place that is subject to large levels of mechanical vibration will not only put added
stress on its components, it may also impede ordinary measurement.
• Flatsurface
Install the MV on a at surface, neither leaning to the left nor to the right. The MV can
be tilted if the stand is used.
Do not install the MV in the following places:
• Outdoors
• Inanenvironmentwithflammableorexplosivegases,steam,ordust
(dangerous places)
• Indirectsunlightornearheatingdevices
Install the MV in a place that is near room temperature (23°C) and that is not subject
to very much temperature uctuation . Placing the MV in direct sunlight or near
heating devices can cause adverse effects on the internal circuitry.
• Inanenvironmentwithexcessiveamountsofsoot,steam,moisture,
dust, or corrosive gases
Soot, steam, moisture, dust, and corrosive gases will adversely affect the MV and
should be avoided.
• Nearstrongmagneticfields
Install the MV in a place with a magnetic eld of less than 400 A/m. Do not bring
magnets or instruments that produce electromagnetic elds close to the MV. Operating
the MV near strong magnetic elds can cause measurement errors.
• Wherethedisplayisdifficulttosee
The MV uses an LCD screen so viewing of the display from an extreme angle is
difcult. Install the MV so that the user can view the display directly from the front.
