The following table lists all the components that make up the document.
Check the instrument operation and response to a source of radiation. The source of radiation may be any material (including consumer products or naturally occurring radioactive material) that generates a response from the instrument. For checking the identification (ID) performance, the radioactive isotope must be known.
Prior to arrival, notify operators concerning expected work and duration.
