Channel Test
While in the NeuroWorks live recording screen, a channel test may be performed to
verify the integrity of the signal processing from the amplifier input through to the display.
A channel test applies a test signal to all channels. This allows you to examine the
waveforms on the screen to see if all of the channels are functioning.
NOTE A channel test does not validate the connection from the patient electrode to the
amplifier input.
