traces of liquid to evaporate.
Inspecting the equipment
Perform the following inspections daily.
•
Check for cracked or broken patient cable, patient electrodes, power cord,
communications cables, display, and enclosure.
• Check for bent or missing pins on all cables.
• Check all cable and cord connections; reseat if any connectors are loose.
Testing the electrocardiograph
Welch Allyn recommends verifying proper operation of the electrocardiograph once a
year to ensure reliability. See Verifying proper operation.
Whenever the electrocardiograph is serviced or whenever problems are suspected,
verify continued electrical safety of the device using IEC 60601-1 or ANSI/AAMI ES1
methods and limits.
WARNING Only qualified service personnel should perform leakage
current tests.
Test for the following:
•
Patient leakage current
• Chassis leakage current
• Earth leakage current
• Dielectric strength (AC and patient circuits)
Replacing the battery
Replace the battery under these circumstances:
•
It loses its charge quickly.
• You have charged it, and the electrocardiograph still does not turn on when
unplugged.
The first time that you press the power button after installing a new battery, the
electrocardiograph goes through some diagnostic tests that cause it to take longer than
usual to power up.
Discard the old battery appropriately. Contact your local authorities concerning recycling.
