Service menu for non-invasive blood pressure
measurement.
Service Data
Pressure shows the measured pressure multiplied by
10. This value is automatically zero-drift
compensated.
Zero shows the difference between the zeroing value
in the permanent memory (stored when the module
is calibrated) and the current automatic zero-drift
compensation multiplied by 10. The value can
change between +20 and -20 mmHg. If the zero drift
exceeds ± 10 mmHg, the module should be
recalibrated.
Protect handle indicates hardware protection for
EEPROM memory. It should be ON all the time in
normal operation. If it is OFF, data cannot be read
from or written to EEPROM, only the calibration
protection can be set or reset by software. It can be
turned to OFF by pressing the NIBP module buttons
Auto ON/OFF and Start Cancel simultaneously for 3 seconds, which also enables Protection ON/OFF menu
selection in the calibration menu.
Calibr. prot. shows software calibration protection and it should be OFF to enable calibration.
+15 V power refers to legacy NIBP modules. Not used in PRESTN series modules and E-PSM(P).
AD0 to AD7 show the values of each eight channels of the A/D converter. AD7 is not used in PRESTN series
modules, M-NIBP module and E-PSM(P).
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 in 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).
