1.4 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 GLT400.
● For stabilized temperature measurement, allow the GLT400 to warm up for at least 30 minutes after
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
GLT400.
● To conduct measurement in noisy environments, connect the GLT400's GND terminal to ground (Refer to
"2.17 Noise Countermeasures".).
● If measured values fluctuate due to noise, set to a slower sampling speed (Refer to "Chapter 4 Settings
and Measurement" – "4.3 Settings screen " – "(3) DATA Settings".).
