2. INSTALLATION
2.1 Mounting Place and External Dimensions
Mount the instrument at the following place so as not to affect the measuring accuracy and recording
operation unfavorably.
1. Industrial environment
Select a place being separated from electric field and magnetic field generation sources and also free of
mechanical vibrations and shocks.
･
OVERVOLTAGE CATEGORY……Ⅱ
･
POLLUTION DEGREE……………2
･
Altitude……………Lower than 2000m
･
Working place…….Indoors
2. Ambient temperature and humidity
Don't expose the instrument to the direct sunlight. Don't enclose the instrument to prevent a temperature
rise.
･Mount the instrument at a stable place where the ambient temperature is about 23°C and the relative
humidity is about 50% RH.
･Mount the instrument at a place free of being exposed to hot blast (higher than 70°C ) for preventing its
door from being deformed.
･Mount the instrument at a place being free of a heat source near its terminals for the purpose of reducing
measuring errors.
3. Atmosphere
･Don't mount the instrument at an inflammable gas atmosphere for securing safety.
･
Don't mount the instrument at any place where dust, smoke, vapor, and other substance exist.
4. Mounting angle and display view angle
