at the source of low-voltage installation.
Measurement category III is for measurement performed
in the building installation.
Measurement category II is for measurement performed
on the circuits directly connected to the low voltage
installation.
Power Supply
WARNING
• Input voltage: 90 ~ 250 V AC, 50/60 Hz
•
The power supply voltage should not fluctuate
more than 10%.
•
Connect the protective grounding conductor of
the power cord to earth ground, to avoid
electrical shock.

Fuse
WARNING
•
Make sure the correct type of fuse is installed
before powering up.
•
Replace the fuse with the specified type and
rating only, for continued fire protection.
•
Disconnect the power cord before fuse
replacement.
•
Make sure the cause of the fuse blowout is
fixed before fuse replacement.
Cleaning PSH • 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 PSH.
• Do not use chemicals or cleaners containing
harsh materials such as benzene, toluene,

This is a Class A product which may cause radio
interference in a domestic environment. In such
case, take adequate measures.
Operation
Environment
WARNING
(Note) EN 61010-1:2001 specifies the pollution degrees
and their requirements as follows. PSH 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.
