Operating Environment
This section describes the environmental conditions and power requirements necessary to use the analyzer.
1.4.1. Environmental Conditions
The analyzer should be only be used in an area which satisfies the following conditions:
•
Ambient temperature: +5
°
C to +55°C (operating temperature range: the internal temperature of the
PC where the R3755x/R3760 is installed)
•
Relative humidity:
80% or less (without 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
The analyzer is designed with full consideration for DC power line noise.
However, it is recommended to use a PC that is located in an environment with minimum line noise. If
line noise cannot be avoided, attach a noise filter to the PC power supply.
•
An area allowing unobstructed air flow
A cooling fan is located in the rear panel of the PC, and vents are located in the side panels and on the
bottom (toward the front) of the PC. Never block the fan and these vents.
Keep the rear panel 10 centimeters away from the wall. In addition, do not use the analyzer upright
turned the rear panel side down. The resulting internal temperature rise will affect measurement accu-
racy.
If exhaust air from the PC is obstructed, the internal temperature may rise resulting in the PC operating
incorrectly.
