Influence of Adjacent Conductor When the frequency of the current in an adjacent conductor is 50 Hz, the
influence on the primary current is 0.5 mA/A or less.
Influence of Conductor Position in the Jaws 0.1% or less in the output signal for a frequency of 400 Hz or less.
Influence of Load Impedance r When 1 Ω < r ≤ 5 Ω, under 0.1% of output signal, and phase shift under 0.2 degrees
Influence of Frequency f
§
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

Under 1% of output signal, given a crest factor of 6 or less for a 2000 A peak
(333 Arms) current or less
Influence of DC Current Superimposed on Nominal Current
Under 1% of the output signal, assuming a current of DC 15 A or less.

Storage Temperature –40°C to +70°C
Temperature Influence 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)
Influence of Humidity Under 0.1% of the output signal given 10% RH ≤ Humidity < 20% RH or
75% RH < Humidity ≤ 90% RH

Measurement category
describes a number which defines a transient overvoltage condition. It implies the
regulation for impulse withstand voltage.
Measurement category III applies to measurement of the distribution level, that is , building wiring, fixed
installations. Measurement category IV applies to measurement of the primary supply level, that is,
overhead lines, cable systems, and so on.
†
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
occures. Occasionally, however, temporary conductivity caused by condensation must be expected.
‡ Reference Conditions
Temperature: 23 °C±3°C
Humidity: 20 to 75% RH
External magnetic field < 40 A/m
No AC magnetic field
Conductor centered in jaws
Load impedance ≤ 1 Ω (≤ 1 VA)
No influence of current flowing in adjacent conductors
When the primary current is sinusoidal, the sinusoidal conditions are: frequency; 48 to 65 Hz, distortion
factor < 1%, no DC component
§ There is no frequency influence 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 affect the functioning of the product.
Four metal surfaces are
