7.1.3 Volume Factor Calibration
Volume Factor calibration must be performed only with an Rp50 resistor
manufactured by Michigan Instruments Inc.
Ventilator might not deliver the correct volume if another Rp50 is used for this
calibration
To calibrate the volume factor:
1.
Connect a patient circuit to the ventilator. Connect the RP50 resistor to the patient
circuit and leave the other end of the resistor exposed to the open air, verifying
that it is not blocked in any way.
2.
Press
Technical
/
and then press
ADVANCED Screen
.
3.
Enter the code
5844
, and confirm by pressing
4.
Press
SERVICE SCREEN
5.
Press
Calibrate Volume
/
Volume Factor
and follow the instructions which appear on
the display.
6.
After pressing Enter /
the ventilator will run volume factor calibration and
display the volume factor value on the screen. The volume factor value should be
between 0.85 and 1.2. Press Enter /
.
7.
Repeat the calibration again and verify that in both cases the volume factor values
are the same. If not repeat the test until 2 consecutive matching volume factor
values are achieved.
If the test fails:
1. Check internal tubing connections for air leaks.
2. Run the following tests:
Pressure sensor calibration
Circuit test
Pressure relief calibration
Volume factor calibration
If Volume Factor is still out of spec, Replace the manifold (see 4.12).
Perform the required calibrations (see 7.3 Test table).
