0.5% at operating frequency, measured at either outputs into 75 Ω terminations.
0.3% of full-scale output.
0.4% of full scale output. This does not include any effects of the CVT.
5 Hz up to 20 kHz
− 0.17 dB max at 5 kHz with respect to gain at operating frequency.
− 0.25 dB max. It will not have DC response.
Less than 1.5 degrees at 3 kHz and less than 3 degrees at 5 kHz. Improved phase response is
offered on request for special applications
150 Ω pure resistive. This corresponds to a maximum voltage at the measurement device (e.g.
power quality monitor) of 3 V rms at a current of 20 mA. The burden may be selected to be any
value up to the maximum to suit the measurement device (the monitor). All figures related to
accuracy and error mentioned in this document would also apply for burdens up the maximum
values.
Differential current output of 20 mA rms, driving 75 Ω through 300 meters of cable.
Cable capacitance is typically 100 pF/m.
