Installation

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.
