Quantities of influence
„ Battery voltage, from 6.5 to 10V: ±6mA/V typical, ±10mA/V max.
„ Temperature, from 0 to 50°C: ±2000 ppm/°C max.
„ Position of the conductor in the window (AC signal at frequency of 1kHz): max ±0.5% of the reading.
„ External magnetic field generated by an AC or DC current of 1A in a conductor in the immediate
vicinity (see typical curve below).
„ Allowance must be made for the linearity, uncertainty, temperature drift, and other errors characteristic
of the oscilloscope when making a measurement.
