Electrical Safety
WARNING
 Make sure the maximum differential voltage
does not exceed 1400V (DC+AC peak) or 450
Vrms for the GDP-025 or 7000V (DC+AC peak)
or 2200 Vrms for the GDP-050/GDP-100
 Make sure the maximum voltage between each
input terminal and ground does not exceed 600
Vrms for the GDP-025 or 6500 Vrms for the
GDP-050/GDP-100
Cleaning the
instrument  The probes do not require any particular
cleaning.
 A soft cloth dampened in a solution of mild
detergent and water can be used to clean the
case.
 Do not spray any liquid into the instrument.
 Do not use chemicals containing harsh products
such as benzene, toluene, xylene, and acetone.
Operation
Environment  Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)
 Relative Humidity: 10 to 85%
 Temperature: 0°C to 50°C
(Pollution Degree) EN 61010-1:2001 specifies pollution degrees and
their requirements as follows. The instrument 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.
