5.1 NIBP service menu
Service Data
Pressure
shows measured pressure multiplied by 10. This value is automatically zero-drift
compensated.
Zero
shows difference between zeroing value in the permanent memory (stored when module is
calibrated) and the current automatic zero-drift compensation multiplied by 10. The value can
change b20 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 can not 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 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 M-PRESTN/M-RESTN/M-PRETN.
AD0
to
AD7
show the values of each eight channels of A/D converter. AD7 is not used in M-
PRESTN/M-RESTN/M-PRETN.
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 monitor broke 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 nonzero
values do not indicate a failure, but the continuous counting (more than 5 per second) indicates
either serial communication failure, or module not in place. Also other modules can cause
communication errors that cause these numbers rise.
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
