Configuration When in Use
Do not use the GL860 standing upright or at an angle. It must always be laid flat or inclined on the stands.
<Usage Configuration>
Laid flat
CAUTION
•
Do not block the air vent on the GL860, as this will cause malfunctioning.
•
Measurement accuracy may not be satisfactory if the system is used in a condition other than described above.
•
To prevent possible toppling, use both of the stands of the GL860 when you place it inclined.
•
Use the GL860 with both of the two stands open as shown in the figure above.

Notes on Temperature Measurement
Please observe the following precautions when performing temperature measurements.
•
Do not block the air vents. Always provide a space of at least 30 cm on all sides of the GL860.
•
For stabilized temperature measurement, allow the GL860 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 GL860.
•
To conduct measurements in noisy environments, connect the GL860's GND terminal to the ground.
(Refer to "2.15 Noise Countermeasures".)
•
If measured values fluctuate due to noise, set to a slower sampling speed.
(Refer to "2. DATA setting" in "3.4 Setting Menus".)
