Autocalibration Failure - MSA SIRIUS Manual De Instrucciones

6 Calibration
7. Push the ON-OFF/ACCEPT button to calibrate (span) the instrument.
• CAL SPAN flashes for approximately 90 seconds.
• If autocalibration sequence passes, the instrument beeps three times and returns
to the Measure mode.
NOTE:
To skip calibration and return to the Measure mode, push the RESET/
button is pushed for 30 seconds, it will return to the Measure page.
8. Remove the tubing from the instrument.
9. Close the valve on the regulator, if so equipped.
10. Repeat steps 5 through 8 for the PID.
NOTE:
The Autocalibration procedure adjusts the span value for any sensor that passes the
test; sensors that fail autocalibration are left unchanged. Since residual gas may be
present, the instrument may briefly go into an exposure alarm after the calibration
sequence is completed.

6.3 Autocalibration Failure

If the SIRIUS Multigas Detector cannot calibrate one or more sensor(s), the instrument
goes into the Autocalibration Failure Page and remains in alarm until the RESET/
is pushed. Sensors that could not be calibrated are indicated by dashed lines on the
concentration display.
Check the calibration cylinder for:
• accuracy
• calibration setpoints
Replace failed sensor or, if a VOC, clean the PID bulb and/or replace the ion chamber.
