Installing the Instrument

• Do not install the instrument outdoors or in locations subject to rain or water.
• Install the instrument so that you can immediately remove the power cord if an abnormal or
dangerous condition occurs.
Installation Conditions
Install the instrument in an indoors environment that meets the following conditions.
Flat and Level Location
Install the instrument on a stable surface that is level in all directions. If you install the instrument
on an unstable or tilted surface, the quality of recordings made by its printer and the accuracy of its
measurements may be impeded.
Well-Ventilated Location
Inlet and 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 and when opening and closing the
cover of the built-in printer, allow extra space for operation.
Ambient Temperature and Humidity

Do Not Install the Instrument in the Following Kinds of Places
• In direct sunlight, or near sources of heat
• In an environment with excessive amounts of soot, steam, dust, or corrosive gases
• Near sources of strong magnetic fields
• Near high-voltage equipment or power lines
• In an environment that is subject to large levels of mechanical vibration
• On an unstable surface
• Outdoors or in locations subject to rain or water
Note
• For the most accurate measurements, use the instrument in the following kind of environment.
Ambient temperature: 23°C ± 5°C Ambient humidity: 30% RH to 75% RH (no condensation)
When using the instrument in a place where the ambient temperature is 5°C to 18°C or 28°C to 40°C, add the
temperature coefficient to the accuracy as specified in chapter 6.
• When installing the instrument in a place where the ambient humidity is 30% or less, take measures to
prevent static electricity such as using an anti-static mat.
• Condensation may form when the instrument is moved from a low temperature/humidity environment to a
high temperature/humidity environment, or when there is a sudden change in temperature. In these kinds
of circumstances, wait for at least an hour before using the instrument, to acclimate it to the surrounding
temperature.
