12. Calibrating
IMPORTANT!
If you are using an IntelliDoX for calibration, wait until the entire operation is complete before
removing the BW Solo. If you undock the instrument too soon, residual gas will give a skewed
reading. If the BW Solo senses this condition, it shows “Purge” followed by “- - -“ on the display for
30 seconds, until the calibration gas is purged and normal measurement can begin.
1. Enter Calibration mode. From the main reading screen, click the button twice in rapid
succession to enter the menus.
2. Click the button until you see Calibrate.
3. 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.
4. If the hose is not connected to the calibration cap and the regulator on the calibration gas
cylinder, attach it now.
5. Hold down the button for 3 seconds. When it enters span value screen, choose “yes” to
change the span value or choose “no” to skip and enter the zeroing process. It performs a
zero calibration.
6. When “Apply Gas” appears on the display, open the cylinder valve by turning the pressure
regulator knob counterclockwise.
7. Start the calibration by pressing and holding the button for 1 second. The calibration is
indicated by a progress bar, followed by “Passed” or “Failed.” You can abort the calibration by
clicking the button once.
IMPORTANT!
If it fails calibration, try calibrating again. If it cannot calibrate after repeated tries, the sensor
may need replacement or there may be a problem with the instrument. Do not use the
instrument until the issue is resolved.
8. When “Turn Gas Off” appears, close the cylinder valve by turning the pressure regulator knob
clockwise.
