Fuse
WARNING
 Fuse type: F1A/250V.
 Only qualified technicians should replace the
fuse.
 To ensure fire protection, replace the fuse only
with the specified type and rating.
 Disconnect the power cord and all test leads
before replacing the fuse.
 Make sure the cause of fuse blowout is fixed
before replacing the fuse.
Cleaning the
function
generator  Disconnect the power cord before cleaning the
function generator.
 Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid
into the function generator.
 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)
and avoid strong magnetic fields.
 Relative Humidity: < 80%
 Altitude: < 2000m
 Temperature: 0°C to 40°C
(Pollution Degree) EN 61010-1:2010 specifies pollution degrees and
their requirements as follows. The function generator 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,
