1.1 Features
(1) Power, current, voltage and watthour measurements in a
single unit
(2) True rms reading of voltage and current values
unaffected by distorted waveforms
(3) Integrator timer can be set in ranges 1 to 99 minutes or 1
to 99 hours. (set timer at 00 for continuous integration)
(4) Auto-zero circuit ensures accurate power and watthour
measurements over long time spans.
(5) Three simultaneous outputs for power, current and
voltage
(6) Connecting the optional 3171 DIGITAL PRINTER to the
data output connector makes it possible to record power
consumption and average power values over time.
