Introduction: Safety Information
1-12
Accuracy of the Input Signal Reproduction
n
Overall System Error is tested using the method
described in AAMI EC11 3.2.7.1. Overall System
Error is +5%.
n
Frequency Response is tested using the method
described in AAMI EC11 3.2.7.2 methods A and
D.
Modulating Effects in Digital Systems
This device uses digital sampling techniques that may
produce some variation in amplitudes of Q, R, and/or S
waves from one heart beat to the next, which may be
particularly noticeable in pediatric recordings. If this
phenomenon is observed, the clinician should be aware
that the origin of amplitude variations is not entirely
physiologic. For measuring voltages of Q, R, and S
waves, it is advisable to use the QRS complexes with the
largest deflection of the particular waves.
Installation and Connection
If the installation of this equipment, in the USA, will use
240 V rather than 120 V, the source must be a center-
tapped, 240 V, single-phase circuit.
