NO CAL DATA, NO CAL Monitor Display
When the ventilator detects invalid or missing calibration records on power up, the NO CAL DATA
alarm is generated. When this happens, default calibration values are used, and although the
ventilator will continue to operate, the accuracy of volumes and pressures may be reduced.
A NO CAL message is posted in place of affected monitored values when the ventilator is operating
without valid transducer calibration data.
When the NO CAL DATA alarm occurs:
• The NO CAL DATA message is flashed in the display window.
• The audible alarm is sounded.
• The ventilator continues to operate.
• Default transducer data is used.
• Vte, PIP, MAP, PEEP, and VE monitored values are displayed as NO CAL.
To clear the NO CAL DATA alarm:
1) Push the Silence / Reset button twice
. This will clear the alarm and the ventilator will continue to
operate; however, the NO CAL message will still be displayed in place of affected monitored
values.
2) Take the unit out of service and perform the Calibration procedure
