Bump Test or Calibration?
Each time you use your gas monitor (that is, put your hands in the life of your gas monitor) you need to do a bump test before use. A bump test is a regular functional test that ensures that your monitor will save your life in the event that hazardous gases make their way into your breathing environment.
A calibration is a periodic test that must be performed by a manufacturer-authorized technician (that's us) to ensure the accuracy of the sensors and readouts of gas monitors. You will be provided with a certificate of calibration to be kept on file when your monitor is returned to you. We recommend that you calibrate electrochemical sensors on a 6 month schedule and infrared sensors on a 12 month schedule. Calibrations are also required any time your instrument fails a bump test.
