Test Operation
After cleaning and inspecting the ELI 150 Rx, proper operation of the unit may be confirmed by using an
ECG simulator to acquire and print a standard 12-lead ECG of known amplitude. Printing should be dark
and even across the page. There should be no evidence of print head dot failure (e.g., breaks in printing
forming horizontal streaks). Paper motion should be smooth and consistent during printing. Waveforms
should appear normal with proper amplitude and without distortion or excessive noise. Paper should stop
with perforations near the tear bar (indicating proper cue sensor operation).
Recommendations to Biomedical Staff
Following any service to the ELI 150 Rx or when non-compliant operation is suspected, Mortara Instrument,
Inc. recommends the following procedures:
• Confirm proper operation.
• Perform testing to ensure continued electrical safety of the device
(use IEC 60601-1 or ANSI/AAMI ES1 methods and limits).
• patient leakage current
• chassis leakage current
• earth leakage current
• dielectric strength (mains and patient circuits)
Battery Maintenance
The ELI 150 Rx houses an internal, sealed lead-acid battery. When installed, the battery has a shelf life
of approximately six months without recharging. If the battery has been stored for a long period in a
discharged state, it may not be able to regain its capacity even if it is recharged.
For information about replacing the battery, please refer to the ELI 150 service manual.
Mortara Instrument, Inc. recommends that the ELI 150 Rx be plugged into AC power whenever possible
to maximize battery life and for the user to develop a habit of recharging the battery before the unit indicates
a “low battery” condition. (That is, reduced depth of discharge.) Battery life varies by how the battery is
maintained and how much it is used. For improved battery life, keep the electrocardiograph plugged in
when not in use.
The sealed lead-acid battery will provide optimum life when the unit is fully charged after each use. The
ELI 150 Rx will charge a depleted battery to 90% of its capacity in approximately 8 hours or less. To
recharge a battery from its lowest level, 30 hours of recharging without operation will be necessary.
