Section 4: Configuration and Service Modes
4- 16
Europe, the South Pacific and other parts of Asia, pressure
calculation algorithm 2 (adjusted) is selected. The pressure
calculation algorithm should be selected to be consistent with
practices used in the country or institution where the N-3100 is
to be used.
4.3.15 Menu Item 29: Instrument Compatibility Report
This function is used by the service technician to display the sensorbus
protocol version and the multicast version. To function properly in a stack,
the N -3100 must have the same protocol version and multicast version as
other instruments in the stack.
1.
From the service mode, select menu item 29 by pressing the UP or
DOWN ARROW buttons. Press the UPPER ALARM LIMIT button. The
SYSTOLIC display will show 29.0 and the DIASTOLIC display will show
a number representing the version and revision of the sensorbus protocol
software in the N-3100. The two digits preceding the decimal point are
the version, and the number following the decimal point is the revision.
2.
Press the UP ARROW button. The SYSTOLIC display will show 29.1 and
the DIASTOLIC display will show a number representing the version
and revision of the multicast software in the N-3100. The two digits
preceding the decimal point are the version, and the number following
the decimal point is the revision.
3.
Press the LOWER ALARM LIMIT button to return to the service mode
steady state.
4.3.16 Menu Item 30: Pressure Transducer Accuracy Test Mode
Note:
Menu items 30 through 36 are discussed in the Performance
Verification section, paragraph 3.3.2, “Verification of Pneumatic
System.” Refer to those procedures for verification standards. The
use of test chambers and the manual inflation pump mentioned in
this section is an optional method of using these service mode menu
items.
The pressure transducer accuracy test verifies the pressure accuracy of the
sensor and requires a 220 cm
3
test chamber, a manometer, and a manual
inflation pump.
1.
Connect the 220 cm
3
test chamber to the N-3100 hose connector.
2.
Using an adapter, connect the manometer and pump in parallel with the
test chamber.
3.
From the service mode steady state, press the UP or DOWN ARROW
buttons until menu item 30 is displayed in the SYSTOLIC display.
4.
Press and release the UPPER ALARM LIMIT button.
5.
Press and release the START/STOP button. The chamber begins to
pressurize to approximately 180 mmHg. The current chamber pressure
in mmHg is displayed in the DIASTOLIC display.
6.
Using the hand pump, manually pressurize the system to approximately
300 mmHg, comparing the manometer readings to the value displayed in
the N -3100 DIASTOLIC display.
