Introduction
4. Notes on Functions and Performance
(1) Be sure to connect the main unit to an AC or DC power supply that conforms to the rated range.
Connecting the device to a non-rated power supply may cause the main unit to overheat and break down.
(2) Do not block the vent on the main unit.
Continued operation with the blocked vent may cause the main unit to overheat and break down.
(3) To avoid malfunctions and other damage, avoid using GL2000 in the following locations.
• Places exposed to high temperature and/or high humidity, such as in direct sunlight or near
heatingequipment.
Allowable temperature range: 0 to 40°C (When AC adapter or battery is operated)
Allowable humidity range: 5 to 85%R.H., non-condensing
• Locations subject to excessive salt spray or heavy fumes from corrosive gas or solvents.
• Excessively dusty locations.
• Locations subject to strong vibrations or shock.
• Locations subject to surge voltages and/or electromagnetic interference.
(4) If the main unit becomes soiled, wipe clean using a soft, dry cloth. Use of organic solvents (such as
thinner or benzene) causes deterioration and discoloration of the outer casing.
(5) Do not use GL2000 in the vicinity of other devices which are susceptible to electromagnetic interference.
(6) Measured results may not conform to the stated specifications if GL2000 is used in an environment which
is subject to strong electromagnetic interference.
(7) Insofar as possible, position GL2000 input signal cables away from any other cables which are likely to be
affected by electromagnetic interference.
(8) For stabilized measurement, allow GL2000 to warm up for at least 30 minutes after turning the power on.
