Maintenance and Service
These units have been tested for electromagnetic compatibility in accordance
with IEC 601-1-2. The failure criterion for the device is, Òundetectable
interference with the ECG trace which could result in misdiagnosis.Ó While the
device passes the relevant standards, it may exhibit evidence of interference
when subjected to electrostatic discharges, high voltage transients or high
voltage surges, as deÞned in IEC 801-2, IEC 801-4 and IEC 801-5. The
interference from a single event will demonstrate as a sharp noise spike on the
ECG trace. The clinician will not confuse such a noise spike with the heart beat
waveforms and there is no hazard of misdiagnosis. In the unlikely situation
that the equipment is placed in an environment where such interference events
are common, either the equipment or the interference source may be moved.
Battery pack
Under normal conditions, a fully charged battery pack provides adequate
power to print a minimum of 200 pages of data at paper speed of 25 mm/sec;
or a minimum of 20 minutes of continuous acquisition and printing.
A fully discharged battery pack will completely recharge in approximately 5
hours.
Heart rate detection
The Eclipse heart rate meter is speciÞed to function in the range of 30 to 250
bpm with a tolerance of ±10% or ±5 bpm, whichever is greater. Question marks
(???) appear on the printout if the heart rate is out of the speciÞed range.
