ACV measurements
Ratio and channel average calculations — Ratio calculates the reading ratio of two
channels, while channel average calculates the reading average of two channels. For these
calculations, paired switching channels are used. Primary channels 1 through 20 are paired
to channels 21 through 40 (channel 1 paired to channel 21, channel 2 paired to channel 22,
and so on). As shown in
channel (i.e., 104) and the other source is connected to its paired channel (i.e., 124).
