Inuence of Adjacent Conductor When the frequency of the current in an adjacent conductor is 50 Hz, the
inuence on the primary current is 0.5 mA/A or less.
Inuence of Conductor Position in the Jaws 0.1% or less in the output signal for a frequency of 400 Hz or less.
Inuence of Load Impedance r When 1 Ω < r ≤ 5 Ω, under 0.1% of output signal, and phase shift under 0.2 degrees
Inuence of Frequency f
5
30 Hz ≤ f < 48 Hz: under 0.5% of output signal
65 Hz < f ≤ 1 kHz: under 1% of output signal
1 kHz < f ≤ 5 kHz: under 2% of output signal
Inuence of Crest Factor Under 1% of output signal, given a crest factor of 6 or less for a 2000 A peak

Temperature Inuence 0.02%/°C or less of the output signal
Operating Humidity 0 to 90% RH (no condensation) However, if 35°C is exceeded, humidity will impair the
primary functionality (by a factor of 0.5% RH/°C)
Inuence of Humidity Under 0.1% of the output signal given 10% RH ≤ Humidity < 20% RH or
75% RH < Humidity ≤ 90% RH

Output Safety jacks (Φ4 mm)
1 This instrument is a measurement category III (600V) product. In this case do not use it for measurement
category IV measurements. This instrument is a measurement category IV (300V) product.
Measurement category O applies to measurement of other types of circuits that are not directly connected
to a main power source.
Measurement Category II applies to electrical equipment that is powered through a xed installation, such
as a wall outlet wired to a distribution board, and to measurement performed on such wiring.
Measurement category III applies to measurement of facility circuits, such as distribution boards and
circuit breakers.
Measurement category IV applies to measurement of power source circuits, such as entrance cables to
buildings and cable systems, for low-voltage installations.
2 Pollution degree describes the degree to which a solid, liquid, or gas which deteriorates dielectric strength
or surface resistivity is adhering.
Pollution Degree 2 applies to the normal indoor atmosphere. Normally, only non-conductive pollution
occurs. Occasionally, however, temporary conductivity caused by condensation must be expected.

4 Reference Conditions
Temperature: 23 °C±3°C Humidity: 20 to 75% RH External magnetic eld < 40 A/m
No AC magnetic eld Conductor centered in jaws Load impedance ≤ 1 Ω (≤ 1 VA)
No inuence of current owing in adjacent conductors
When the primary current is sinusoidal, the sinusoidal conditions are: frequency; 48 to 65 Hz, distortion
factor < 1%, no DC component
5 There is no frequency inuence in the range 48 Hz ≤ f ≤ 65 Hz.

6. Maintenance
• Note the following when cleaning the probe.
• Do not clean the probe while clamped to a conductor. Likewise, do not clean while
connected to a measuring instrument.
• Do not allow water to contact the jaws.
• When opening the jaws, keep the exposed metal areas clean. If dust accumulates, wipe with a
clean dry cloth. To prevent rust, wipe metal surfaces with oil from time to time. Avoid getting oil on
non-metallic surfaces. Use only high quality, low-viscosity machine oil such as sewing machine oil.
• This product undergoes a 100% inspection at the time of shipment. If any layers of the core
come apart slightly during shipment, this will not a󰀨ect the functioning of the product.
Four metal surfaces are
exposed with the clamp
