General
Guideline

CAUTION

 Do not place any heavy object on the

instrument. Note: Only 2 units can be stacked
vertically.

 Avoid severe impact or rough handling that

leads to damaging the instrument.

 Do not discharge static electricity to the

instrument.

 Use only crimped wires, not bare wires, for the

terminals.

 Do not block the cooling fan opening.

 Do not disassemble the instrument unless you

are qualified.

 The equipment is not for measurements

performed for CAT II, III and IV.

(Measurement categories) EN 61010-1:2010 specifies the
measurement categories and their requirements as follows.

 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.

 0 is for measurements performed on circuits not

directly connected to Mains.

 Do NOT position the equipment so that it is

difficult to disconnect the appliance inlet or the
power plug.

 If the equipment is used in a manner not

specified by the manufacturer, the protection
provided by the equipment may be impaired.

WARNING

 AC Input voltage range: 100-120VAC/200-

240VAC
(90-132VAC/180-250VAC)

 Frequency: 47-63Hz

 Power:

PEL-3021(H): 90VA Max
PEL-3041(H): 110VA Max
PEL-3111(H): 190VA Max
PEL-3211(H): 230VA Max

 To avoid electrical shock connect the protective

grounding conductor of the AC power cord to
an earth ground.

 To avoid electric shock, the power cord

protective grounding conductor must be
connected to ground. No operator serviceable
components inside. Do not remove covers.
Refer servicing to qualified personnel.

Cleaning

 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 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

 Humidity: 0 to 85% RH

 Altitude: <2000m

 Overvoltage category II

PEL-3000(H) User Manual

(Pollution Degree) EN 61010-1:2010 specifies the 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.

Storage
environment

 Location: Indoor

 Temperature: -20°C to 70°C

 Humidity: <90% RH

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.
