Safety Guidelines
General
Guideline
CAUTION
Do not place any heavy object on the PEL-2000B
series.
Avoid severe impact or rough handling that
leads to damaging the PEL-2000B series.
Do not discharge static electricity to the PEL-
2000B series.
Do not block or obstruct the cooling fan vent
openings.
Do not perform measurement at circuits directly
connected to Mains (Note below).
Do not disassemble the PEL-2000B series unless
you are qualified as service personnel.
The equipment is not for measurements
performed for CAT II, III and IV.
(Measurement categories) EN 61010-1 specifies the measurement
categories and their requirements as follows. The PEL-2000B series
falls under category I.
Measurement category IV is for measurement performed 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.
Measurement category I is for measurements performed on
circuits not directly connected to Mains.
Power Supply
WARNING
AC Input voltage range: 100-120Vac/ 200-
240Vac (90-132Vac/ 180-250Vac)
Frequency: 47~63Hz
Power rating: PEL-2004B: 250VA Max
PEL-2002B: 150VA Max
Connect the protective grounding conductor of
the AC power cord to an earth ground, to avoid
electrical shock.

Fuse
WARNING
Fuse type: T3.15A/250V
Make sure the correct type of fuse is installed
before power up.
To avoid fire, only replace the fuse with the
specified type and rating.
Disconnect the power cord before fuse
replacement.
Make sure the cause of a fuse blowout is fixed
before replacing the fuse.
Cleaning the
PEL-2000B
Disconnect the power cord before cleaning.
Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid.
Do not use chemicals or cleaners containing
harsh material such as benzene, toluene, xylene,
and acetone.
Operation
Environment
Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)
Temperature: 0°C to 40°C
Altitude: Up to 2000m
Transient Overvoltage on the main supply is
2500V.
(Pollution Degree) EN 61010-1 specifies the pollution degrees and
their requirements as follows. The PEL-2000B series 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.
Storage
environment
Location: Indoor
Relative Humidity: < 80%
Temperature: −10°C to 70°C
Disposal
Do not dispose this instrument as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased. Please make sure
discarded electrical waste is properly recycled to
reduce environmental impact.
