Connecting to your Electrical System
The 61-805 power analyzer can be configured for three types of electrical systems: three-phase systems, aron systems
(rotary input), and single-phase systems. Enclosed are connection diagrams for each of these electrical systems.

Operating the Power Analyzer
All measured values, as well as maximum and minimum, can be read on a 160 x 160 pixel, liquid, crystal display. Data
is viewed on a variety of screens. Pressing the [ESC] key will change the screen view on the power analyzer.

kW (active power)
The active power is calculated from instantaneous voltage and current data. The readout gives the instantaneous values
of the active power of each phase and also the three phase total instantaneous active power, which is the addition of each
phase value.
