How long does a Bump Test take?
On some units, manually, a bump/challenge test will take between 3-5 minutes for the sensors to respond fully and activate the alarms. Typically with this style of bump test, it requires a written record of testing to support.
Some manufacturers (MSA 4X/5X) as little 10-15 seconds. But these units have datalogging which means the unit records the test which can be downloaded later or uploaded via a calibration dock automatically.
Some units, even with a calibration dock can take 2-3 minutes (BW) and still require a written record to be maintained.

What else should I consider when challenge testing my portable gas detector?
Complete an external check of your detector by checking the:
- sensor filters - are not blocked with dirt, mud, chemicals or any other foreigh substance that will impede the sensors from responding to gases in the atmosphere
- external housing - missing screws and cracks in the houseing or LCD screen
- missing parts - clothes clip, compliance/certification sticker
These might not seem like much but they can influence the integrity of your unit.
