Revision C MAC 1200/1200 ST 14-9
2012250-021
Technical Specifications: Recording
ECG Calibration
Automatic recording of a defined voltage step, valid for all channels.
Calibration voltage, referred to ECG signal input: l mV
Calibration pulse width on recording depends on paper speed
25 mm/s 5 mm
50 mm/s 10 mm
5 mm/s l mm
Automatic ECG Gain Adjustment
The gain automatically adapts to the incoming signal. The maximum
amplitude of the lead group or of all leads determines the gain setting.
Automatic adjustment range5 ... 40 mm/mV
Amplitude range (6 channels) 18 to 31 mm
Baseline
Automatic adjustment of the baseline to the optimal recording range, in
dependence of the signal amplitude.
Anti-drift System (ADS)
Automatic compensation of baseline fluctuations caused by polarization
voltage fluctuations at the lead electrodes (delay in recording: 4.2
seconds).
ECG Storage
In Automatic mode, storage of approximately 40 ECGs.
Stored ECGs can be deleted (individually or all in one pass), printed,
transferred and patient data can be edited.
In Arrhythmia mode, storage of up to 6 event episodes.
Blocking
Rapid charge reversal of the coupling capacitors in the preamplifiers
after electrode application.
