Hey everyone today we're looking at how to calibrate and bump test the Honeywell BW (BW Technologies) GasAlert Extreme NH3 (Ammonia) monitor.

If you have a problem during your calibration, give us a call or send it in for repair here:

Calibration Steps:
1. Turn the BW GasAlert Extreme on in normal reading mode by pressing and holding the power button.
2. Once the BW GasAlert Extreme is in normal reading mode, you need to send it into calibration mode. Do this by pressing and holding the Gray Down Arrow (2nd button in from the left) and the blue circle (Button furthest to the right) at the same time. A count down will begin.
3. This will send the monitor into zeroing mode. Now is a good time to set the monitor down, and grab your calibration gas, regulator, and calibration adapter.
4. Open the valve on your regulator. This is a very important step so you do not ruin your calibration gas cylinder. Now screw it in to your calibration gas cylinder. Close the regulator once you hear gas spewing out of it. This is the signal to know your regulator is good to close. Continue screwing in the regulator until it stops. Do not overturn it.
5. After the BW GasAlert Extreme is zeroed, attach the tubing to the hose barb on your regulator. Make sure the tubing is also connected to your calibration adapter.
6. Make sure your calibration gas values on the screen match what is on your calibration gas cylinder!
7. Once the BW GasAlert Extreme has finished calibration, the BW GasAlert Extreme will beep, disconnect your tubing and turn off the gas.
8. Congratulations! You have officially calibrated your BW GasAlert Extreme gas monitor. Make sure to record these readings in your calibration log!
