For voltage ranges from 10 V to 300 V, the change in reading
due to a change in frequency is not greater than ± 3% over
the range 15 Hz to 15 kHz. This is in addition to the accuracy
figure specified for 50 Hz.
Typically 1 second to full scale
Variation due to external magnetic fields is within the limits of BS 89 1977
0,01 Ω per lead (approx.) for standard Megger test leads.
