• Operating Environment
Figure 1-1 Operating Environment
The R3765/67G series should be installed in an area which satisfies the following canditions:
• Ambient temperature : +5°C to +40°C (Operating temperature range: When FDD is used.)
0°C to +50°C (Operating temperature range: When FDD is not used.)
-20°C to +60°C (Storage temperature range)
• Relative humidity : PH80% or less (no condensation)
• An area free from corrosive gas
• An area away from direct sunlight
• A dust-free area
• An area free from vibrations
• A low noise area
Although the R3765/67G series has been designed to withstand a certain amount of noise
riding on the AC power line, it should be used in an area of low noise. Use a noise cut filter
when ambient noise is unavoidable.
For highly accurate measurement, turn the power ON after the R3765/67G series temperature
has reached the room temperature level, and warm up the R3765/67G series for 30 minutes.
• Installation position
The R3765/67G series has an air outlet hole on its rear panel. Never block or plug the hole, as
the resulting internal temperature rise will affect measurement accuracy.
• Avoid operation in the following areas. • Use a noise cut filter when there is a large
amount of noise riding on the power line.
