STEP 1: The checked fields show
the channels that will have
waveforms recorded should a
trigger occur. This cross-trigger
function prevents recording of
meaningless data from unused
(disabled) channels.
• Press to select the Volts or
Amps channel matrix. The
channels selected for the matrix
will be displayed. Each matrix
assigns a different group to
trigger and save. See NOTE
describing the characteristics of
each channel matrix.
Check/Uncheck a channel field
to enable/disable channel for
waveform capture. Proceed to
Step 2.
