Anti-drift system (ADS) (cubic spline)
automatic compensation of baseline fluctuations caused by polarization voltage fluctuations at the
lead electrodes (delay in recording: 4.2 s)
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
e when memory is full user is informed of the possible actions
Blocking
rapid charge reversal of the coupling capacitors in the preampiifiers after electrode application
ensures that the baseline is guickly 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
charging during line-power operation from integrated AC adapter module
