Bump Test
1. Connect the calibration hose to the 0.5l/min regulator on
the gas cylinder.
Note
Only use the calibration cap for bump tests and calibrations.
2. Connect the calibration hose to the intake inlet on the
calibration cap. Arrows on the calibration cap indicate
the direction of gas flow.
3. Attach the calibration cap and tighten the knob.
Figure 9. Tightening the Calibration Cap
Note
Ensure the knob is securely fastened before applying gas. Do
not overtighten the calibration cap. Ensure strong air currents
are kept away from the exhaust side of the calibration cap, as
this can affect the bump test accuracy.
4. Apply gas. Verify the visual, audible, and vibrator alarms
activate.
5. Close the regulator and remove the calibration cap from the
detector. The detector will temporarily remain in alarm until
the gas clears from the sensors.
6. Disconnect the calibration hose from the cap and regulator.
