3.2 Installing the Instrument
WARNING
You should never run the instrument in an upright position, with the fan vent facing
downward. If the instrument malfunctions while in this position, heat escaping from the
vent may cause a fire. If you really need to operate the instrument in this position, place
a metal plate or flame-retardant barrier (grade UL94-1 or higher) beneath it.
Installation Conditions
Be sure to install the instrument in a location that meets the environmental conditions described
below.
Ambient temperature and humidity
Ambient temperature and humidity during operation should be within the following limits.
• Temperature: 5
°
C to 40
°
C
For high accurate measurement: 23
±
2ºC
• Humidity: 20% to 80% RH; no condensation
For high accurate measurement: 50
±
10% RH
Note
Condensation may occur when the instrument is moved from a cold, dry location to a warm, humid one or
when there is a rapid change in ambient temperature. If liquid condenses on the instrument, allow the
instrument to stand for at least one hour under stable ambient conditions before using.
Well-ventilated location
Vent holes are situated on the top and bottom of the instrument. In addition, vent holes for the
cooling fans are also situated in the rear panel. To prevent a rise in the internal temperature, the
vent holes should not be blocked and sufficient clearance should be maintained around them.
