Distortion parameters

I 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 to
10 kHz. See graph of typical error as a function of the frequency, in appendices, page 62.
I Battery voltage: ≤ 0.1% / V
I Temperature: ≤ 300 ppm /°C or 0.3% /10°C
I Humidity 10...85% RH at ambient temperature: ≤ 0.1% rdg
I Position of a conductor of ∅ 20 mm :
I Adjacent conductor carrying an AC current 50 Hz, at 23 mm from the clamp: < 10 mA/A
I Distortion of an external field of 400 A/m (50 Hz) on centred cable: < 1.3 A
I Common mode rejection: > 65 dB A / V
I Residual magnetism: < 4 mA/A
