Power Supply
WARNING
•
AC Input voltage: 100 ~ 240V AC, 47 ~ 63Hz
•
The power supply voltage should not fluctuate
more than 10%.
•
Connect the protective grounding conductor of
the AC power cord to an earth ground.
Fuse
WARNING
•
Fuse type: T1A/250V
•
To ensure fire protection, replace the fuse only
with the specified type and rating.
•
Disconnect the power cord before replacing the
fuse.
•
Make sure the cause of fuse blowout is fixed
before replacing the fuse.
Cleaning the
oscilloscope
•
Disconnect the power cord before cleaning the
oscilloscope.
•
Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid
into the oscilloscope.
•
Do not use chemical containing harsh products
such as benzene, toluene, xylene, and acetone.

(Pollution Degree) EN 61010-1:2001 specifies the pollution
degrees and their requirements as follows. the oscilloscope
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.
