BW Defender2 User Manual Calibration and Setting Alarm Setpoints • Calibrate a new sensor before use. Allow the sensor to stabilize before starting calibration (used: 60 seconds; new: 5 minutes). • Calibrate the detector once every one to three months, depending on use and sensor exposure to poisons and contaminants. • Calibrate the detector if the ambient gas display varies at start-up. • It is best to calibrate the sensor before changing alarm setpoints.
BW Defender2 Calibration and Setting Alarm Setpoints Diagnostics Protection: The detector test the ambient air (auto zero) and the test gas applied (auto span) to ensure it meets expected values. In auto zero if any background target gas is present, the sensor(s) affected will read no and exit the auto zero function retaining the previous set value(s).
BW Defender2 User Manual Calibration Procedure Auto Zero and Oxygen Sensor Calibration To calibrate the detector and set its alarm setpoints, perform the following procedure. The display flashes “auto zero” while the detector automatically zeroes the H2S, CO and LEL sensors and calibrates the oxygen sensor. Start Calibration To quit at any point after auto zero, press . The detector retains any saved values, and the audible alarm beeps four times before the detector returns to normal operation. 1.
BW Defender2 Calibration and Setting Alarm Setpoints Pass Code Protect: The detector will ask for the pass code before proceeding to Auto Span and Alarm Setpoints. If the pass code is not entered within 8 seconds or the wrong pass code is entered, the detector advises the code is not correct. Pass Code Protect Activated Before setting span the display will advise Calibration is locked. Then display requests the Pass Code. The detector beeps four times and automatically returns to normal operation.
BW Defender2 User Manual Auto Span Note The display shows a flashing gas cylinder and beeps twice, prompting you to apply a calibration gas to the sensor or skip the span (sensitivity adjustment): Use a calibration gas containing the gas concentrations listed in the Guidelines. Apply gas to the sensor at a flow rate of 250 to 500 ml/min. 2. Or, press e d now to skip the span.
BW Defender2 Calibration and Setting Alarm Setpoints Alarm Setpoints Alarms may be set anywhere within the detection range for the sensor (See specifications), or set to zero for OFF.
