Notes on Temperature Measurement

Please observe the following precautions when performing temperature measurement.
●
Do not block the air vents. Always provide a space of at least 30 cm on all sides of the GL220.
●
For stabilized temperature measurement, allow the GL220 to warm up for at least 30 minute safter
turning it on.
●
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
GL220.
●
If measured values fluctuate due to external noise, try the countermeasures described on page 2-16.

Notes on Using the Monitor

The monitor is an LCD display unit, and so the display will vary depending on the operating environment.
1.6

Changing the Display Language

You can choose either English, Japanese, French, German, Chinese, or Korean as the language displayed on
the screen. The default display language is set to English when the GL220 is shipped overseas. To change the
display language, see the instructions in "OTHR:Language".

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.
• Condensation may form on the LCD screen if the GL220 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.
