It can measure RMS voltage, current, active power, apparent power, reactive power, energy accumulation, energy timing, frequency, and power factor.
The working error is ±(0.1% reading + 0.1% range) for voltage and current.
No, the relay output is an optional feature; the 8716B1 and 8775A1 models can be extended with it.
The maximum peak value for voltage and current is 1.6 times the maximum range.
