3. Calibrate the detector before first time use and then on a regular schedule depending on use and sensor exposure to poisons and contaminants BW recommends at least once every 180 days 6 months BW recommends to bump test the sensors before each day s use to confirm their ability to respond to gas by exposing the detector to a gas concentration that exceeds the high alarm setpoints Manually verify that the audible and visual alarms are activated Calibrate if the readings are not within the specified limits It is recommended that the combustible sensor be checked with a known concentration of calibration gas after any known exposure to catalyst contaminants poisons sulfur compounds silicon vapors halogenated compounds etc GasAlertMicro Users Manual A Cautions cont The combustible sensor is factory calibrated to 50 LEL methane If monitoring a different combustible gas in the LEL range calibrate the sensor using the appropriate gas High off scale LEL or v v methane readings may indicate an explosive concentration Protect the combustible sensor from exposure to lead compounds silicones and chlorinated hydrocarbons Although certain organic vapors such as leaded gasoline and halogenated hydrocarbons may temporarily inhibit sensor performance in most cases the sensor will recover after calibration Any rapid up scaling reading followed by a declining or erratic reading may indicate a gas concentration be
