A bump test is a quick procedure in which a gas monitor is exposed to a known concentration of a target gas to ensure that the gas triggers the alarm at the set level. More often than not, the reading on the screen will not perfectly mirror the specs on the bottle of target gas, but as long as the variation is within 10%, we can consider the monitor to function within the acceptable range.

Bump testing analyzes the natural response of stator end-windings upon excitation from a mechanical impulse. The conductors, the bars and the complete stator end windings can be considered as a mechanical spring-mass-damper system, and therefore all have specific natural frequencies that depend on the rigidity, mass and damping.

If it fails this bump test, then you should go ahead and try to perform a full calibration, now using an appropriate gas standard. If the unit cannot be calibrated, it must be taken out of service. Fair enough, except if the instrument passes the bump test, and depending on the gas in question and the range involved, the actual calibration could still be off—perhaps significantly.

In order to perform a bump test there are two ways. Turn on the monitor. Wait for the monitor to completely boot up so that the sensors are showing on the display in Normal Mode. Press both [Y/+] and [N/-] key at the same time and hold them for about 5 seconds

Not sure what you mean by a bump test? A calibration is using a known value and adjust your instrument accordingly. Depending on the instrument to be calibrated, we may proceed a little differently but the principle is the same. For example, a spe...

Performing a bump test will require the use of a calibration kit which consists of a 4-gas calibration cylinder, a 0.5 LPM regulator, a calibration cup and some non-absorbent sample tubing. The standard 4 gas cylinder used for this testing will consist of 50% LEL methane, 12% oxygen, 25ppm H2S, 50ppm CO and a balance of nitrogen.
