In what order should you proceed to ensure proper function of a direct reading instrument?

The correct sequence begins with inspecting the instrument, ensuring that it is free of any visible damage or obstructions that could affect its operation. Next, checking the battery is crucial to confirm that it has sufficient power for accurate readings.

Following that, checking the alarm system ensures that any alerts for dangerous levels of hazardous materials will be functioning correctly, which is vital for safety during operations. Once these preliminary steps are completed, calibrating the instrument is necessary to ensure that it provides accurate readings based on the specific conditions it will encounter.

Finally, returning to background readings allows the technician to establish a baseline from which any changes can be monitored effectively. This systematic approach not only enhances the reliability of the readings but also reinforces safety protocols when working in environments with hazardous materials.
