Operation
US
If a sensor is nearing its end of life, this "
SPAN PASS
" indication will be followed by the end of sensor
life warning (
symbol). The
symbol, and the gas type of the sensor nearing its end of life, will blink
for 15 seconds when the device returns to Normal Operation mode. When in Normal Operation mode,
the
symbol is continuously displayed.
Finishing Calibration
(1)
Close the valve on the regulator.
(2)
Remove the calibration cap.
The calibration procedure adjusts the span value for any sensor that passes the calibration test;
sensors that fail calibration are left unchanged. Since residual gas may be present, the device may
briefly go into an exposure alarm after the calibration sequence is completed.
Autocalibration Failure
If the span calibration is unsuccessful:
•
If the device cannot calibrate one or more sensor(s), it goes to the SPAN ERR page and remains
in alarm until the
button is pressed.
•
A sensor life indicator is displayed (Alarm symbol and
symbol) to show the sensor has reached
its end of life and should be replaced.
This occurs if the span calibration is unsuccessful twice.
•
The device will remain in alarm state until the
button is pressed.
•
The Alarm symbol and
symbol will remain on the display until a successful calibration or sensor
in question is replaced.
•
After the
SPAN
calibration completes, the
device momentarily displays
“
SPAN PASS
” or “
SPAN ERR
” along with
the label of any sensor that failed then
returns to Normal Operation mode.
A span calibration can fail for many reasons besides sensor at the end of his life. If a
span calibration failure occurs, items such as remaining gas in the calibration cylinder,
gas expiration date, security of the calibration cap, etc. should be verified and calibration
should be repeated prior to replacing the sensor.
