Power freq: Set power frequency; 50 Hz/60 Hz.
Filter low
: Set filter low frequency; 0.05 Hz/0.5 Hz.
Filter high: Set filter high frequency; 30 Hz (40 Hz if
power freq is 60 Hz) /100 Hz or 150 Hz @ NE12STPR.
Service Data
Power freq, and Cable type show the values chosen
or detected, Filter low and high defines the selected
filter (Monitor/Diagnostic/ST).
Quick zero at PRESTN series module is ON when the
ECG signal is beyond the scale, and therefore, is
quickly returned to optimal range using fast signal
processing methods. All the Quick zero bits are ON at
the same time.
Cable shows ON when ECG cable is connected.
Electrode shows ON when each of these electrodes
are connected.
Pacer count is a running number for pacemaker
users.
Button No effect on the module.
Resp Available indicates that ECG hardware is capable of measuring impedance respiration.
Measurement shows ON when the respiration measurement is on.
Amp zero shows ON when zeroing of the respiration amplifier takes place.
Waveform VALUE will be updated in one second interval.
Timeouts is a cumulative number that indicates how many times the module has not responded to the
monitor’s inquiry.
Bad checksums is a cumulative number that indicates how many times communication from the module to the
monitor has broken down.
Bad c-s by mod is a cumulative number that indicates how many communication errors the module has
detected.
The monitor starts counting these items at power up and resets to zero at power off. The values may also be
reset when a module is attached to the monitor frame and be set to 32769 or continuous counting may be
started when the module is removed from the monitor frame.
The nonzero values do not indicate a failure, but the continuous counting (more than 5 per second) or value
32769 indicates either a serial communication failure or a module not in place. Also failures in other modules
may cause these numbers to rise or be set to 32769.
RAM indicates the state of the RAM memory.
ROM indicates whether the checksum at the EPROM is in accordance with the one the software has calculated.
EEPROM indicates if the values stored in the permanent memory are valid.
The state is either OK, Fail or ? (module not in place or a communication error).
