Power Supply
WARNING

AC Input voltage: 100-240 VAC 50/60Hz

The power supply voltage should not fluctuate
more than 10%.

Connect the protective grounding conductor of
the AC power cord to an earth ground, to avoid
electrical shock.
Cleaning the
Instrument

Disconnect the power cord before cleaning.

Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid.

Do not use chemicals containing harsh material
such as benzene, toluene, xylene, and acetone.
Operation
Environment 
Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)

Temperature: 0°C to 40°C

Humidity:
< 30°C: < 80%RH(non-condensing);
30°C~40°C: <70%RH(non-condensing);
>40°C: <50%RH (non-condensing)

Altitude: <2000m
(Note) EN 61010-1:2010 specifies the pollution degrees and their
requirements as follows. The GBM-3000 SERIES falls under degree
2.

Pollution refers to “addition of foreign matter, solid, liquid, or
gaseous (ionized gases), that may produce a reduction of
dielectric strength or surface resistivity”.

Pollution degree 1: No pollution or only dry, non-conductive
pollution occurs. The pollution has no influence.

Pollution degree 2: Normally only non-conductive pollution
occurs. Occasionally, however, a temporary conductivity caused
by condensation must be expected.

Pollution degree 3: Conductive pollution occurs, or dry, non-
conductive pollution occurs which becomes conductive due to
condensation which is expected. In such conditions, equipment
is normally protected against exposure to direct sunlight,
precipitation, and full wind pressure, but neither temperature
nor humidity is controlled.
