Accuracy 10% R + 5 counts
NB : Base frequency : For triangular and square signals, with a 50% cyclical ratio, at 50Hz
± 1Hz and at 60Hz ± 1Hz, the accuracy in % of the reading (R) is 3% R + 2 counts.
Frequency range
The input signal must be stationary and the fundamental between 45Hz and 65Hz.
Outside this frequency range or if the signal is not stationary, display of
same time as the displayed value, to indicate that the measurement is outside the
specified range.
Response time of the digital display : one value per second.
Permitted overload and warning signal : idem Currents and Voltages.
