Accuracy is specified for 0 V to 7 V rms, dc or 1 kHz sine wave input with the AD536A connected as in the figure referenced.
2
Error vs. crest factor is specified as an additional error for 1 V rms rectangular pulse input, pulse width = 200 μs.
3
Input voltages are expressed in volts rms, and error is expressed as a percentage of the reading.
