1.3 Measurement Category
Measurement Category
This instrument can make measurements in Measurement Category I.
WARNING
This instrument can only be used for measurements within its specified measurement
categories.
Measurement Category Definitions
• Measurement category I is for measurements performed on circuits not directly
connected to MAINS. Examples are measurements on circuits not derived from
MAINS, and specially protected (internal) MAINS derived circuits. In the latter
case, transient stresses are variable. Thus, you must know the transient withstand
capability of the equipment.
• Measurement category II is for measurements performed on circuits directly
connected to low voltage installation. Examples are measurements on household
appliances, portable tools and similar equipment.
• Measurement category III is for measurements performed in the building
installation. Examples are measurements on distribution boards, circuit-breakers,
wiring (including cables, bus-bars, junction boxes, switches and socket-outlets) in
the fixed installation, and equipment for industrial use and some other

equipment. For example, stationary motors with permanent connection to a
fixed installation.
• Measurement category IV is for measurements performed at the source of a
low-voltage installation. Examples are electricity meters and measurements on
primary overcurrent protection devices and ripple control units.
1.4 Ventilation Requirement
This instrument uses a fan to force cooling. Please make sure that the air inlet and
outlet areas are free from obstructions and have free air. When using the instrument
in a bench-top or rack setting, provide at least 10 cm clearance beside, above and
behind the instrument for adequate ventilation.
CAUTION
Inadequate ventilation may cause an increase of temperature in the instrument, which
would cause damage to the instrument. So please keep the instrument well ventilated and
inspect the air outlet and the fan regularly.

Protection Level Against Electric Shock
ESD ±8kV
Installation (Overvoltage) Category
This product is powered by mains conforming to installation (overvoltage) category II.
WARNING
Ensure that no overvoltage (such as that caused by a bolt of lightning) can reach the
product. Otherwise, the operator might be exposed to the danger of an electric shock.
Installation (Overvoltage) Category Definitions
Installation (overvoltage) category I refers to signal level which is applicable to
equipment measurement terminals connected to the source circuit. Among these
terminals, precautions are done to limit the transient voltage to a low level.
Installation (overvoltage) category II refers to the local power distribution level which
is applicable to equipment connected to the AC line (AC power).
Pollution Degree
Pollution Degree 2
Pollution Degree Definition
• Pollution Degree 1: No pollution or only dry, nonconductive pollution occurs.
The pollution has no effect. For example, a clean room or air-conditioned office
environment.
• Pollution Degree 2: Normally only nonconductive pollution occurs. Temporary
conductivity caused by condensation is to be expected. For example, indoor
environment.
• Pollution Degree 3: Conductive pollution or dry nonconductive pollution that
becomes conductive due to condensation occurs. To be found in industrial
environment or construction sites (harsh environments). For example, sheltered
outdoor environment.
• Pollution Degree 4: The pollution generates persistent conductivity caused by
conductive dust, rain, or snow. For example, outdoor areas.

6. Test the other channels in the same way. If you see the waveform, but the square
wave is not shaped correctly as shown above, perform the procedure described in
Probe Compensation . If you do not see the waveform, perform those steps again.
WARNING
To avoid electric shock when using the probe, please make sure that the insulated wire of
the probe is in good condition. Do not touch the metallic part of the probe when the
probe is connected to high voltage source.
