GasAlertMicroClip User Manual Activating the Detector Audible/Visual Test 1. To activate the detector, press C in a normal clean atmosphere. The LCD shows all the display elements as it beeps, flashes, vibrates, and briefly turns on the backlight. Self-Test Once the detector is activated, it performs the following checks. Manually verify that all actions occur. Battery Test The detector administers a battery test during start-up.
GasAlertMicroClip Activating the Detector Note Users can enter a 2-line message, up to a maximum of 25 characters per line. The message appears on the LCD after the detector version displays. This option is disabled in the factory settings. The message can be enabled or changed in the Sensors tab in Soft Tools. See GasAlertMicroClip Soft Tools instruction sheet. 4. Alarm Setpoints 3. Sensors and Power Test The detector then tests the sensors.
GasAlertMicroClip User Manual Note The sensors are continuously tested while the detector is activated. Automatic Zero and O2 Calibration (optional) 5. The sensors (H2S, CO, and LEL) are automatically zeroed and the O2 sensor is automatically calibrated (unless it is disabled in the detector’s options). The detector beeps twice to signal a successful zero and span. Note If ambient air is set to be measured 20.8% vol., the automatic oxygen calibration screen displays 20.8 instead of 20.9.
GasAlertMicroClip Activating the Detector Note Calibration can also be performed by using BW Technologies by Honeywell’s MicroDock II. Cal Lock Enabled Press C to acknowledge the warning and enter normal operation, or continue with the self-test if applicable. If the Cal Lock option is enabled, an infrared (IR) device is required to calibrate the detector. IR--LOCK displays as the detector tries to establish a connection with an IR device (e.g.
GasAlertMicroClip User Manual If any of the sensors need to be bump checked, the detector displays the following screen: Bump Check (optional) Note Bump check is not performed if the detector was just calibrated (step #6). BW recommends to “bump check” 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 alarm setpoints. If the bump interval is set to 0, the bump check start-up feature is bypassed. 7.
GasAlertMicroClip Activating the Detector While the LCD displays BUMPCHK todAY, apply gas to the detector or press C to deactivate the detector. If gas is applied to the detector, the detector needs to enter alarm for the bump check to be accepted. Once the bump check has been accepted, the detector enters normal operation. Self-Test Fail Once the detector enters normal operation, the LCD displays which sensor has failed the self-test by displaying Err above the target gas bar.
GasAlertMicroClip User Manual Backlight Options The LCD’s backlight automatically activates when there is an alarm condition. Pressing C activates the backlight in any condition. To access the user options, connect the detector to the IR Link adapter and use the GasAlertMicroClip Soft Tools software. Refer to the GasAlertMicroClip Soft Tools manual for complete instructions. Deactivating the Detector To deactivate the detector, press and hold C while it beeps and flashes to the corresponding countdown.
GasAlertMicroClip Options Detector Identification Start-up Message This option allows you to personalize your detector. In the Detector Identification group there are two fields available for you to enter a message: Startup Message Top Line; and Startup Message Bottom Line. If a message is entered, it appears during the start-up sequence after the detector version is displayed.
GasAlertMicroClip User Manual Calibration Gas Concentration Bump Interval The calibration span gas option (Cal Gas) allows you to input a new gas concentration for each sensor. Refer to the values listed on your calibration gas cylinder. The Bump Interval determines the number of days before a sensor needs to be bump checked. A different interval value can be selected for each sensor. Set the interval value to 0 to disable this option. This option is disabled upon shipment.
GasAlertMicroClip Options TWA Alarm Automatic O2 Calibration The TWA Alarm option allows you to select the timeweighted average (TWA) alarm setpoint for either the H2S or CO sensor. Refer to Resetting Gas Alarm Setpoints for the factory alarm setpoints. When the O2 Auto-Calibration on Startup option is enabled, it forces the detector to automatically calibrate the oxygen sensor upon activating the detector. The automatic calibration option is enabled upon shipment.
GasAlertMicroClip User Manual User Options Menu Confidence Beep The Confidence Beep notifies that the detector is on and the battery has sufficient power to respond to a hazardous level of gas to emit an alarm. Instead of beeping when the battery power is low, the audible alarm beeps once every 10 seconds to advise that the battery has sufficient power. The confidence beep stops when the battery power is low. This option is disabled upon shipment.
GasAlertMicroClip Options Low Alarm Acknowledge Force Bump When Overdue When Low Alarm Acknowledge is enabled, the audible alarm can be disabled during a low alarm if C is pressed, but the vibrator and alarm LEDs continue to be enabled. This option is not applicable to the O2 sensor. When enabled, the Force Bump When Overdue option forces a bump check if the sensor has exceeded its bump check interval (see Bump Interval). If a successful bump check has not been performed, the detector will deactivate.
GasAlertMicroClip User Manual If more than one type or level of alarm exists at the same time, a multi-gas alarm will result. Alarms The following table describes the detector alarms and shows how the LCD looks for each alarm. To change the factory-set alarm setpoints, refer to the GasAlertMicroClip Soft Tools instruction sheet. During an alarm condition, the detector activates the backlight, audible/visual/vibrator alarms, and the LCD shows the current ambient gas reading. Table 6.

Confirm with your supervisor before clearing TWA and STEL alarms. To clear the TWA, STEL, and MAX exposure readings, press C when the LCD displays RESET.
GasAlertMicroClip User Manual Resetting Gas Alarm Setpoints Gas Alarm Setpoints Note The detector's gas alarm setpoints trigger the gas alarms that are described in the table below. To change the alarm setpoints, you must connect the detector to the IR Link adapter and use the GasAlertMicroClip Soft Tools software. Refer to the GasAlertMicroClip Soft Tools manual for complete instructions. Table 8.
GasAlertMicroClip Alarms Stopping a Gas Alarm Low Battery Alarm The low and high alarms stop when the ambient gas level returns to the acceptable range. The detector tests the battery on activation and continuously thereafter. Battery power is continually displayed during normal operation. If the battery voltage is low, the detector activates the low battery alarm. Note If alarms are set to latch, press C to reset the alarms.
GasAlertMicroClip User Manual • Calibrate the detector at least once every 180 days, depending on use and sensor exposure to poisons and contaminants. When calibrating the detector, adhere to the following guidelines: • Calibrate the detector if the ambient gas display varies at start-up. • • It is best to calibrate the sensor before changing the alarm setpoints. • Calibrate only in a safe area that is free of hazardous gas.
GasAlertMicroClip Calibration Diagnostics Protection Wind currents may cause false readings and poor calibrations. The detector tests the ambient air (auto zero) and the test gas that is applied (auto span) to ensure it meets expected values. If an unexpected level of target gas is present during an auto zero, the auto zero will fail for that sensor. The detector advises which sensor(s) failed the auto zero before proceeding to the auto span.
GasAlertMicroClip User Manual Calibration Procedure 1. In a clean atmosphere, press and hold C as the detector beeps, flashes, and vibrates to the corresponding OFF countdown. Continue to hold C as the detector briefly deactivates. 2. The detector then reactivates and performs the CAL countdown. Continue to hold C until the CAL countdown is complete to enter calibration. To calibrate the detector perform the following procedure. Note Calibrate O2 in clean air.
GasAlertMicroClip Calibration Auto Zero and Oxygen Sensor Calibration Note Auto Span 4. The LCD now prompts you to apply calibration gas to the sensors. 5. K flashes and remains displayed as you attach the calibration cap and apply gas to the sensors at a flow rate of 250 to 500 ml/min. (refer to Figure 3. Applying Gas to the Sensors). Do not apply calibration gas at this point, otherwise auto zero may fail for that sensor and then it cannot be spanned. 3.
GasAlertMicroClip User Manual When the detector senses a sufficient amount of gas concentration (approximately 30 seconds), the flashes, and K audible alarm beeps once, remains lit while the detector completes the span (approximately 2 minutes). No Gas Detected The LCD displays FAILURE if the detector does not detect any gas within 2 minutes before proceeding with the calibration procedure.
GasAlertMicroClip Calibration If you apply gas to a sensor and the detector fails to span the sensor, repeat the calibration procedure using a new gas cylinder. If the sensor fails the span a second time, replace the sensor. See the section, Replacing a Sensor or Sensor Filter. Calibration Due Date Note The number of days shown in the last screen represents the earliest date a calibration needs to be performed.
GasAlertMicroClip User Manual Verification • Peak exposure level (ppm or %); After calibration is complete and the detector is in normal operating mode, test it using a gas cylinder other than the one used in calibration. The gas concentration should not exceed the sensor's detection range. Confirm that the LCD shows the expected concentration. To ensure the readings are accurate, apply the test gas for the same amount of time as was applied to the sensor when it was calibrated.
GasAlertMicroClip Maintenance Charging the Detector a Warning the following figure. The detector can be activated during charging. ⇒ The detector must be charged in a nonhazardous atmosphere of 32°F - 113°F (0°C - 45°C). ⇒ Charge the detector using only the recommended charging adapter.
