Operating Environment

This section explains the operating environment for the GL220

Ambient Operating Conditions

(1) Ambient temperature and humidity (the GL220 must be operated within the following ranges.)
• Temperature range: 0 to 45°C (0 to 40°C when battery pack is mounted)
• Humidity range: 5 to 85% RH
(2) Environment (do not use in the following locations.)
• A Location such as being exposed to direct sunlight
• Locations exposed to salty air, corrosive gases, or organic solvents
• Dusty locations
• Locations subject to vibration or impact
• Locations subject to voltage surge or electromagnetic interference such as lightning or electric furnaces
(3) Installation category (overvoltage category)
• The GL220 belongs to Installation Category II defined in IEC60664-1.
• Never use the GL220 for Installation Category III or IV.
(4) Measurement category
• The GL220 belongs to Measurement Category I defined in IEC61010-1.
• The GL220 cannot be used for Measurement Category II, III, or IV.

Warming-up Before Use

The GL220 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

It is recommended to use the GL220 while it is laid flat or inclined on the stands.
Usage Configuration
If condensation occurs...
Condensation occurs in the form of water droplets on the device surfaces and interior when the GL220 is
moved from a cold to a warm location. Using the GL220 with condensation will cause malfunctioning.
Wait until the condensation has disappeared before turning on the power.
Laid flat
To prevent possible malfunction, do not block the air vents of the GL220.
If you use the GL220 in other position than described in the above, the measurement accuracy may not
meet the specifications.
To prevent possible toppling, use both of the stands of the GL220 when you place it inclined.
Use the GL220 with both of the two stands open as shown in the figure above.
