Hello,

"_Off" signals are lead detection channels. If the signal is above or below a pre-set threshold, then either the positive or negative lead of the channel has come off. If values are reading within the preset ranges, the lead is considered valid. These channels are specific to the manufacturer, and further details are not disclosed in their specifications.

Best,

Stephanie
