16.6 Cyclic Impedance Check
This measures the exact impedance of each individual electrode. It causes a disturbed EEG
wave, and a prompt message is displayed on the monitor
The cyclic impedance check is automatically initiated when a sensor is connected. To
manually start a cyclic impedance check manually, you can either:
Select [Cyc Imped. Check] in the [BIS Setup] menu and then select [On].
Press the hardkey on the BIS module.
Select [Start Cyc Imped. Check] in the BIS sensor window.
The cyclic impedance check stops automatically if the impedances of all electrodes are
within the valid range. To manually stop a cyclic impedance check, you can either:
Select [Cyc Imped. Check] in the [BIS Setup] menu and then select [Off]
Press the hardkey on the BIS module.
Select [Stop Cyc Imped. Check] in the sensor check window.
