General Description
1.4 Notes on Temperature Measurement
Please observe the following precautions when performing temperature measurement.
(1) Do not block the air vents. Always provide a space of at least 30 cm on all sides of the GL450.
(2) For stabilized temperature measurement, allow the GL450 to warm up for at least 30 minutes
after turning it on.
(3) Exposure of the input terminals to direct drafts, direct sunlight, or abrupt changes in
temperature may impair the equilibrium of the input parts and result in measurement errors. To
measure temperature in such an environment, take appropriate countermeasures such as
changing the installation site of the GL450.
1.5 Notes on Using the Monitor
The monitor is an LCD display unit, and so the display will vary depending on the operating environment.
CHECKPOINT
If the screen saver function is used, it will operate and clear the screen if no operations are performed
during the preset time. If the screen saver operates, press any key to restore the display.
CAUTION
• Condensation may form on the LCD screen if the GL450 is moved from a cold to a warm location. If
this occurs, wait until the LCD screen warms up to room temperature.
• The LCD screen is manufactured to extremely high precision. Black dots may appear, or red, blue,
and green dots may not disappear. Likewise, streaks may appear when viewed from certain angles.
These phenomena are due to the LCD screen construction, and are not signs of a fault.
1.6 Changing the Display Language
You can choose either English, French, or Japanese as the language displayed on the screen. The default
display language is set to English when the GL450 is shipped overseas. To change the display language,
see the instructions in "Changing the Display Language".
