EEG Machine Care: Daily, Weekly and Annual Maintenance

An EEG machine is a long-term investment. A simple maintenance routine keeps recordings clean, prevents breakdowns and extends the life of the equipment.

Daily

• Clean electrodes after each patient. Remove paste with warm water and a soft brush, disinfect as per protocol and dry fully.
• Inspect leads and connectors for cracks, kinks or loose pins.
• Wipe the headbox and cables with a slightly damp cloth (never spray liquid directly).
• Back up recordings to an external drive or server.

Weekly

• Run the amplifier self-test or calibration signal if available.
• Test all electrodes for impedance on a test board or a volunteer.
• Clean electrode caps thoroughly and let them air-dry.
• Check that the PC has enough free space for recordings.

Monthly

• Install software updates approved by the supplier.
• Check the photic stimulator and the video camera, if fitted.
• Review the earthing and the UPS battery status.
• Audit consumables (paste, gel, abrasive, tape, disposable electrodes).

Annually

• Preventive maintenance by a qualified engineer: electrical safety, amplifier performance and connector inspection.
• Replace worn electrodes and caps.
• Renew the AMC or CMC once warranty ends. See our AMC vs CMC guide.

Do’s and don’ts

• Do store electrodes loosely coiled, never tightly wound.
• Do keep the machine covered when not in use.
• Don’t pull electrodes by their wires.
• Don’t run the machine on unstable power without a UPS.
• Don’t install unrelated software on the acquisition PC.
