ECG storage
in 12 Lead Mode, storage of up to 40 ECGs
• stored ECGs can be deleted (individually or all
in one pass), printed, transferred, and patient
data can be edited
• when memory is full user is informed of the
possible actions
Blocking
rapid charge reversal of the coupling capacitors in
the preamplifiers after electrode application,
ensures that the baseline is quickly restored to its
original position after overranging
Electrode monitoring
audible and visual indication on the LCD of
disconnected electrodes or line break; each single
electrode is monitored
Text input
patient and user data as well as comments can be
entered via the panel keyboard and are annotated
on the recording strip
Copy function
after ECG recording in 12 Lead Mode, copies of
the ECG can be printed from memory and/or
transferred to a MUSE CV system (configurable)
Test
automatic performance test upon power up,
including verification of the signal path starting at
the signal input
stored test ECG data for demonstration of the
device functions
Power supply
from the power line or from a built-in rechargeable
battery, automatic switchover; automatic battery
