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 into the
GDM-8245.
 Do not use chemicals or cleaners containing harsh
material such as benzene, toluene, xylene, and
acetone.
Operating
environment
 Location: Indoor, no direct sunlight, dust free, almost
non-conductive pollution (Note below)
 Relative Humidity: < 75%
 Altitude: < 2000m
 Temperature: 0°C to 50°C (operation)
(Note) EN 61010-1:2001 specifies the pollution degrees and their
requirements as follows. The GDM-8245 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.
