1200 resting ECG analysis system Revision D

2012250-095
Specifications: Basic Information
ECG Calibration
Automatic recording of a defined voltage step, valid for all channels.

Calibration voltage, referred to ECG signal input: 1 mV
Calibration pulse width on recording depends on paper speed
25 mm/s: 5 mm
50 mm/s: 10 mm
5 mm/s: 1 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 range: 5 to 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) (Cubic Spline)
Automatic compensation of baseline fluctuations caused by polarization voltage
fluctuations at the lead electrodes (delay in recording: 4.2 seconds).
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.
