Page 14: Wearing The Instrument
Self-test — Between regular calibration procedures, Industrial Scientific also recommends calibration immediately following each of these occurrences: the installation of a new (or replacement) sensor; the unit falls, is dropped, or experiences another significant impact; is exposed to water; fails a bump test; has been exposed to an over-range (positive or negative) gas concentration. - Page 15 The instrument performs a self-test during power on. If set to always-on, the instrument will perform a self-test every 24 hours. The self- test can be completed on demand by the worker. Note: The use of calibration gases not provided by Industrial Scientific may void product warranties and limit potential liability claims.

Page 45: Maintenance Definitions
Appendix A Maintenance Definitions Bump Test (or "functional test") Bump testing is a functional test in which an instrument's installed sensors are to be briefly exposed to (or “bumped” by) calibration gases in concentrations that are greater than the sensors’ low-alarm setpoints. This will cause the instrument to go into low alarm and will indicate which sensors pass or fail this basic test for response to gas. -
