UG-194
The Line Cycle Accumulation window is also accessible from
the Active Energy window (see Figure 11).
Figure 11. Line Cycle Accumulation Window
The line cycle mode allows energy to be accumulated over an
integral number of half line cycles. To activate line cycle accu-
mulation, an ac signal must be present on the voltage channel.
Click EXIT in the CF Outputs or Line Cycle Accumulation
window to return to the Active Energy window.
REACTIVE ENERGY
The Reactive Energy window is available from the MENU box.
This window is similar to the Active Energy window shown in
Figure 10, but it allows access to registers that are associated
with the reactive energy measurements. Tabs are available to
select Current Channel A or Current Channel B registers. The
CF Outputs and Line Cycle Accumulation windows are also
accessible from the Reactive Energy window (see Figure 9 and
Figure 11, respectively).

APPARENT ENERGY
The Apparent Energy window is available from the MENU
box. The Apparent Energy window allows access to the regis-
ters associated with the apparent energy measurement (see
Figure 13). Tabs are available to select Current Channel A or
Current Channel B registers.
The CF Outputs and Line Cycle Accumulation windows
shown in Figure 9 and Figure 11 are also accessible from
the Apparent Energy window.
Apparent energy measurement is derived from the product
of the current rms and voltage rms measurements. The RMS
window can be accessed from the Apparent Energy window
by clicking Voltage RMS or Current RMS (see Figure 12).
Figure 12. RMS Window
From the RMS window, the calibration and configuration regis-
ters associated with the VRMS and IRMS measurements can be
accessed. In addition, the rms readings can be obtained. Click
EXIT in this window to return to the Apparent Energy window.
