3.1. REFERENCE CONDITIONS

Quantity of influence
Temperature
Relative humidity
Frequency of the signal measured
Type of signal
External electric field
External DC magnetic field (earth field)
External AC magnetic field
Position of the conductor
Shape of the measurement coil
Input impedance of the oscilloscope

3.2. ELECTRICAL CHARACTERISTICS

Range - I nominal (Arms)
Wrapping diameter (mm)
Output/input ratio (mV~/A~)
Range of use (A)
Specified measurement range (A)
Maximum peak factor
Uncertainty
Residual noise at I = 0 (Arms)
Max. phase shift at 1 kHz (°)
Max. output voltage (Vpeak)
Output impedance (kΩ)
(1): Peak factor: PF = Vpeak/Vrms.
(2): The residual noise affects the measurement uncertainty according to the formula:
global uncertainty =
If the current measured is zero, the uncertainty is equal to the residual noise.
