Technical Data
ECG Storage:
Circular input memory for 10 s, 12-lead ECG.
Frequency Range of Digital Recorder
0 to 150 Hz (IEC);
0 to 150 Hz (AHA)
ECG Amplifier:
Simultaneous, synchronous registration of all
9 active electrode signals (= 12 standard leads)
Sampling frequency:
1000 Hz
Digital resolution:
5 µV
Dynamic range:
±10 mVAC
Max. electrode potential:
±300 mVDC
Time constant:
>3.2 s

Myogram Filter (muscle tremor filter):
25 Hz or 35 Hz, programmable (not active on averaged waveform). The stored ECGs can
be printed with or without filter.
Line Frequency Filter:
Distortion-free suppression of superimposed 50 or 60 Hz sinusoidal interferences by
means of an adaptive digital filter.
