If condensation occurs...
Condensation occurs in the form of water droplets on the device surfaces and interior when the GL820 is
moved from a cold to a warm location. Using the GL820 with condensation will cause malfunctioning.
Wait until the condensation has disappeared before turning on the power.
Warming-up Before Use
The GL820 should be allowed to warm up with the power turned on for approximately 30 minutes to ensure
that it operates according to the specified performance.
Configuration When in Use
Do not use the GL820 standing upright or at an angle. It must always be laid flat.
Usage Configuration
Do not block the air vent on the GL820, as this will cause malfunctioning.
Measurement accuracy may not be satisfactory if the system is used in a condition other than described
above.
