11.Bump Testing

IMPORTANT! BUMP TEST THE MONITOR BEFORE EACH DAY’S USE

Prior to each day’s use, every gas detection monitor should be bump tested to confirm the response of all sensors and activation of all alarms by exposing the monitor to a concentration of target gas that exceeds the low alarm set point. A bump test is also recommended if the monitor has been subjected to physical impact, liquid immersion, an Over Limit alarm event, or custody changes, or anytime the monitor’s performance is in doubt.

To ensure greatest accuracy and safety, only bump test and calibrate in a fresh air environment. The monitor should be calibrated every time it does not pass a bump test, but no less frequently than every six months, depending on use and exposure to gas and contamination, and its operational mode

• Calibration intervals and bump test procedures may vary due to national legislation.
• Honeywell recommends using calibration gas cylinders containing the gas that is appropriate to the sensor you are using, and in the correct concentration.

1. From the main reading screen, click the button twice in rapid succession to enter the menus.
2. Click the button until you see Bump.
3. Press and hold the button down for 3 seconds. The instrument counts down and then performs an AVV (audible, visible, vibration alarm) test. You see “Passed” or “Failed” on the display
4. Press and hold the button to acknowledge the results. You should see “Apply Gas?”
5. Press the button to initiate the test.
6. Place the calibration cap over the Honeywell BW Solo, and hook the cap’s left clip to the corresponding groove of the detector and press down on the tab to snap the right clip into place.

7. If the hose is not connected to the calibration cap and the regulator on the calibration gascylinder, attach it now.
8. Open the cylinder valve by turning the pressure regulator knob counterclockwise.

9. Press and hold the button to initiate the bump test. A progress bar indicates that the bump test is happening.

• If the instrument passes the bump test, the message “Passed” appears.
• If the instrument fails the bump test, the message “Failed” appears.

10. When “Turn Gas Off” appears, close the cylinder valve by turning the pressure regulator knob clockwise
11. Remove the calibration cap by pulling on the tab.

If the sensor does not pass a bump test, repeat the bump test. If it fails repeated bump tests, perform a full calibration. If it does not pass a full calibration, the sensor may need replacement. Do not use the instrument until it passes a full calibration.
