• Wiring unit Σ measurement functions
The following 24 measurement functions are available.
UΣ (average voltage): UrmsΣ (rms value),* UmnΣ (rectified mean value calibrated to the rms value),* UdcΣ
(simple average), UacΣ (AC component)
IΣ (av
erage current): IrmsΣ (rms value),* ImnΣ (rectified mean value calibrated to the rms value),* IdcΣ (simple
average), IacΣ (AC component)
PΣ (total active power), SΣ (total apparent power), QΣ (total reactive power), λΣ (average power factor), φΣ
(average phase difference)
WPΣ (total integrated power), WP+Σ (total positive integrated power), WP-Σ (total negative integrated power),
qΣ (total integrated ampere-hour), q+Σ (positive total integrated ampere-hour), q-Σ (negative total integrated
ampere-hour),
WSΣ (total apparent energy), WQΣ (total reactive energy), ZΣ (average impedance), RSΣ (average series
resistance), XSΣ (average series reactance), RPΣ (average parallel resistance), XPΣ (average parallel
reactance)
* Y
ou can select either the rms value or the rectified mean value calibrated to the rms value (but not both). In
either case, the value is displayed as rms.
