3.2 Installing the Instrument
WARNING
• This instrument is designed to be used indoors. Do not install or use it outdoors.
• Install the instrument so that you can immediately remove the power cord if an
abnormal or dangerous condition occurs..
CAUTION
If you block the inlet or outlet holes on the WT3000, the WT3000 will become
hot and may break down.
Installation Conditions
Install the instrument indoors that meets the following conditions.
• Flat, Even Surface
If the instrument is not installed on a stable horizontal surface, the printer’s recording
quality may degrade and precise measurements may be impeded.
• Well-Ventilated Location
Inlet/Vent holes are located on the top and bottom of the instrument. To prevent
internal overheating, allow at least 20 mm of space around the inlet and vent holes.
When connecting measurement wires and other various cables or when opening or
closing the built-in printer cover, allow extra space for operation.
• Ambient Temperature and Humidity
Ambient temperature: 5 to 40° C
Ambient humidity: 20 to 80%RH (when the printer is not used)
35 to 80%RH (when using the printer)
No condensation in either case.
• Do not install the instrument in the following places:
•Outdoors.
• In direct sunlight or near heat sources.
• Where the instrument is exposed to water or other liquids.
• Where an excessive amount of soot, steam, dust, or corrosive gas is present.
• Near strong magnetic field sources.
• Near high voltage equipment or power lines.
• Where the level of mechanical vibration is high.
• On an unstable surface.
Note
• For the most accurate measurements, use the instrument in the following environment.
Ambient temperature: 23±5°C Ambient humidity: 30 to 75%RH (no condensation)
When using the instrument in a place where the ambient temperature is 5 to 18°C or 28 to
40°C, add the temperature coefficient to the accuracy as specified in chapter 12.
• When installing the instrument in a place where the ambient humidity is 30% or below, take
measures to prevent static electricity such as using an anti-static mat.
• Condensation may occur if the instrument is moved to another place where the ambient
temperature is higher, or if the temperature changes rapidly. In this case, let the instrument
adjust to the new environment for at least one hour before using the instrument.
