Understanding When a Signal is Acquired

2-4 Revision 0.1

2Notes for Customers Using Disposable Electrodes

Disposable electrodes have conductive material on the adhesive side only. The

electrode tab must be placed between the jaws of the electrode adapter clip, and

remain flat. Do not attempt to place the jaws of the electrode adapter so close to the

circular part of the electrode that the tab of the electrode is bent, or contact is made

with the conductive gel. Gently tug on the electrode adapter to ensure that the

electrode adapter is properly placed on the electrode.

Good and accurate placement on the first attempt should be your goal for each

electrode. Each time an electrode is lifted off the skin and attached again, the

adhesive gel becomes weaker and less effective.

Never mix reusable and disposable electrodes on the same patient.

2Understanding When a Signal is Acquired

Your cardiograph attempts to acquire a good signal for an Auto report before you

press the key to start an ECG recording. Agilent calls this Pre-acquisition.

Pre-acquisition is activated when the cardiograph is turned on and remains active

until an Auto report begins to print. Pre-acquisition is suspended whenever an

electrode is disconnected.

Pre-acquisition is reactivated when key is pressed to halt any cardiograph

activity. When Pre-acquisition is active, it is important for the patient to stay still

and relaxed. This helps ensure a good signal is captured prior to recording an Auto
