Use scenarios - On-site slope measurement: press Hold to capture a stable reading, switch units between degrees and slope percentage to prepare reports, and use acoustic reminders to stay informed without watching the screen constantly. - Laboratory or workshop testing: toggle between degree and slope percentage to compare results, hold a measurement for record-keeping, and enable sound reminders to signal when measurements are complete or ready for review. - Training or classroom demonstrations: students practice reading values with Hold to compare multiple readings, use the unit switch to learn conversions, and enable reminders to guide the session pace.
