SPAN calibration starts. • After the SPAN calibration completes, the device momentarily displays COMB/EX COMB/EX “SPAN PASS” or “SPAN ERR” along with the label of any sensor that failed then returns to the Measuring mode. 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 measure mode. When in measure mode, the ♥ symbol is continuously displayed. If the span calibration is unsuccessful: • A sensor life indicator displays ( symbol and ♥ symbol) to show the sensor has reached its end of life and should be replaced. • The device will remain in alarm state until the p button is pressed. • The symbol and ♥ symbol will remain on the display until a successful calibration or sensor in question is replaced. 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. 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 ca-libration 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 ca-libration sequence is completed. Altair 4X Multigas Detector...
