IMPORTANT! BUMP TEST THE MONITOR
Prior to 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.
