Connections
• direct connection for measurement of one pressure
• connection via adapter for measurement of two pressures
Display
• pressure waveform with 25 mm/s sweep for both channels
• pressure waveform for the following pressure sites: arterial (ART1, ART2), pulmonary
artery (PA), venous (VEN), left-atrial (LAP), intracranial (ICP) for ART, PA and LAP the
systolic, diastolic and mean values can be displayed
• display update interval: 2 seconds
Signal processing
Pressure
• measuring range -30 to +300 mmHg
• resolution 0.25 mmHg, internal
• cut-off frequency 12 Hz
• accuracy ±2 mmHg ±1% of actual value
• zero drift < ±0.1 mmHg/°C
• 5 minutes to warm up for full accuracy
Zero balancing
• automatic compensation of the transducer value for a zero pressure in both channels,
every channel to be zeroed is checked for absence of pulse signals
• balancing initiated after key press > 2 seconds
• balancing range ±100 mmHg
• storage of the balancing value for 5 minutes after power failure or when monitor is
switched off
• deviation < ±1 mmHg
• initiation only when signal modulation < ±1 mmHg
