Distortion parameters

Maximum distortion of the frequency on the measurement (to be added to the error in the
reference range): 1% rdg from 65 to 440 Hz, 3.5% rdg from 440 to 2000 Hz and -3 dB from
2 kHz to 10 kHz. See graph of typical error as a function of the frequency, in appendices,
page 66.
Battery voltage: ≤ 0.1% / V
Temperature: ≤ 300 ppm /°C or 0.3% rdg /10°C
Humidity 10...85 % RH at ambient temperature: ≤ 0.5%
Position of a conductor of ∅ 20 mm : from DC...440 Hz
Adjacent conductor carrying an AC current 50 Hz, at 23 mm from the clamp: < 10 mA/A
Distortion of an external field of 400 A/m (50 Hz) on centred cable: < 1.3 A
Common mode rejection: > 65 dB A / V
Residual magnetism: < 4 mA/A
