Impedance Check
An impedance check is performed to ensure that the electrode contact with the patient is satisfactory. You can perform an
impedance check at any time during a study.
Running an Impedance Check from the Software
When an impedance check is initiated, the software scans all channels (in auto scan mode).
To… Do this…
Start the impedance check Choose Controls > Impedance Check
Lock onto a channel Click Lock Channel . Then adjust the electrode connection until
satisfactory levels are achieved
Proceed to a full impedance check Click Release Lock
End the impedance check Click End
Save the impedance check as part of the study Click
End and Start Recording
An impedance check displays bar graphs that show the impedance of each electrode connection. A green bar indicates that the
reading is below the set threshold. A red bar indicates the reading is above the threshold. To set the impedance threshold, click
one of the Threshold buttons in the Threshold Group box on the right side of the Check Impedance box.
