Computed Channel
A computed channel performs mathematical operations on the readings from measurement channels, or
other computed channels. To configure, press Channel and use the knob or right arrow key to select one
of the computed channels (channels 401 through 420).
You must configure the measurement channel(s) before performing the mathematical operations in
the computed channel.
Monitoring of computed channels is only available during scanning and will only display the reading
from the most recent sweep.
Press In Scan to specify whether the computed channel is included in (On) or excluded from (Off) the scan
list. Press Equation to specify the equation to be used for the computed channel. The equations choices
can be categorized in three main groups:
