Step 4. The software has an option where the LOFF_STATP and LOFF_STATM Registers are

continuously polled (set the Read Status Registers switch as shown in shown in Figure 43).

This option allows the user to see the lead-off detection scheme work in real time. Figure 44

shows a case for which only positive electrodes are connected.
