Monitor the Test

Once the test begins:

User should monitor the live data stream and keep track of test timing
User may be pause and resume the test at any time
User may restart the test from the beginning
User may upload a partial session if a full session cannot be completed

Monitor Data Stream

Data will be displayed and recorded from the 7 active electrodes: FZ, CZ, PZ, F3, P3, F4, and P4.

Top

Stimulus Counter

The stimulus counter will display the current epoch (or tone) and will count up until finished

Top

Pause & Resume

Click Pause Test to pause the test at the current epoch

Click Resume Test to resume test at the current epoch

Top

Session Duration

Displays the total time the test has been running.

Top

Data Viewing Options

Uncheck boxes to disable viewing impedance, stimuli, artifacts or button presses from the Monitor screen.

Top

Upload Full or Partial Session

Upload Session button will become enabled after a test session is completed
Click Upload Session to upload the data
User may click Quit Session>Upload Partial Session to upload a test before it finishes

NOTE: This should only be done if Patient cannot continue or complete test, a Patient Report will not be creatable from a Partial Test Session.

Type	Description	Display	Corrective Action	Key
Cable Error	Occurs when the HCU is not connected to the Harness with the HCU Cable.	CHECK CABLE! PRESS >	Connect the HCU to the Harness with the HCU Cable	>
Memory Error	Occurs when a test is run unusually long and the memory becomes completely full of data.	OUT OF MEMORY! PRESS >	The test will terminate and the data can then be uploaded. Press:	>
Battery Too Low	Occurs at HCU boot up.	BATTERY TOO LOW PLEASE WAIT...	Plug the HCU back into the charger and allow to charge.
Impedance Error	Occurs when an electrode (1, 2, 3, 4, 5, 6, 7, R) has an impedance too high to run the test (>70kΩ). See Troubleshooting Artifacts	CHECK 1234567R < RECHECK OK >	Reprep the scalp for the referenced electrode and press:	>
	The test will continue normally after the referenced electrode has been reprepped.	EPOCH N/M
Artifact Error	Occurs when any electrode channel (1, 2, 3, 4, 5, 6) records an EEG signal above the Artifact Threshold (default = ±100µV). See Troubleshooting Artifacts	ARTIFACT 123456!	The test will automatically rerun the portion of the test where the artifact occurred. No action is required unless the Max Errors (default = 50) is exceeded.
Max Errors	Occurs when the total number of epochs run exceeds the Max Errors preset (default = 50). See Troubleshooting Artifacts	MAX ERRORS! PRESS >	The test will terminate with the Error status. To upload the data recorded up until this point, press:	>
Max Test Duration	Occurs when the total test time exceeds the Max Test Duration preset (default = 30min). See Troubleshooting Artifacts	TEST TIME IS UP! PRESS >	The test will terminate with the Error status. To upload the data recorded up until this point, press:	>
Incorrect Button Press	For ERP paradigms which require the patient to press a button in response to a specific stimulus, the patient may not perform the task or may perform the task incorrectly.		Pause the test by pressing and holding for 3 seconds:	O
		TEST WILL PAUSE AT END OF EPOCH...
		END SESSION 0 < RESET RESUME >	When the test pauses, remove an Earphone and give the button instructions to the patient again. Replace the Earphone and press:	>
