WVRC-8 Installation and Operation Manual
SETUP
Virtual Channel Setup Dialog
The WVRC-8 lets you define up to four “virtual” channels. These are similar to
analog channels, but their values are derived from the product of two real analog
channels and a constant.
Label
Changes the label associated with any of the virtual channels.
Units
Changes the engineering units label of any virtual channel.
Analog 1
Selects the first of two analog (metering) channels used in the cal-
culation.
Analog 2
Selects the second of two analog (metering) channels used in the
calculation.
Constant
Specifies the constant used in the calculation.
OK
Saves the settings and exits.
Cancel
Exits without saving settings.
Example: Assume analog (metering) channel 1 shows voltage in volts and analog
(metering) channel 2 shows current in amps and an efficiently factor of 72%. You
would define a virtual channel showing indirect power in Watts by setting
Label=Indirect Power, Units=”Watts”, Analog (metering) 1=Voltage, Analog
(metering) 2=Current, Constant=0.72
