GasAlertMicro. Refer to the user manual on the accompanying CD-ROM for complete operating instructions. The GasAlertMicro gas detector (“the detector”) warns of hazardous gas at levels above user-selectable alarm setpoints. The detector is a personal safety device. It is your responsibility to respond properly to the alarm. Note The detector is shipped with English as the displayed language. The Portuguese, Spanish, German, and French guides have their screenshots displayed in the corresponding language. Safety Information - Read First Use the detector only as specified in this guide, otherwise the protection provided by the detector may be impaired. Read the following Cautions before using the detector. a Cautions ⇒ Warning: Substitution of components may impair Intrinsic Safety. ⇒ Caution: For safety reasons, this equipment must be operated and serviced by qualified personnel only. Read and understand the user manual completely before operating or servicing. ⇒ 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). * See Specifications

2 ⇒ 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.). ⇒ Only the combustible gas detection portion of this instrument has been assessed for performance. ⇒ 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. ⇒ Caution: High off-scale readings may indicate an explosive concentration. ⇒ Electromagnetic interference may cause incorrect operation under certain circumstances. ⇒ 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 beyond upper scale limit, which may be hazardous. ⇒ Do not change or charge batteries in a hazardous location. Doing so will impair the Intrinsic Safety of the unit and may lead to fire or explosion. ⇒ For use only in potentially explosive atmospheres where oxygen concentrations do not exceed 20.9% (v/v). ⇒ Extended exposure of the GasAlertMicro to certain concentrations of combustible gases and air may stress a detector element, which can seriously affect its performance. If an alarm occurs due to high concentration of combustible gases, recalibration should be performed, or if needed, the sensor replaced.

and H simultaneously and hold for 5 seconds. The detector beeps 4 times. The detector then beeps once more signifying that calibration has started. 4. Press H or G to change the alarm setpoint. Press A to skip to the next setpoint. Press C to save. The detector beeps four times at the end of the alarm setpoint stage. 2. The display flashes N while the detector zeroes the H2S, CO, and combustible sensors. The detector beeps twice at the end of the auto zero stage. 5. Press H or G to change the next calibration due date. Press C to save. The detector beeps five times indicating that calibration is complete. 3. When the display flashes K, connect the calibration bottle and apply gas at a flow rate of 250 to 500 ml/min. The detector beeps three times at the end of the span stage. Remove the calibration gas. Note The calibration cap should only be used during the calibration process.
