Acoustic reminders can be turned on or off, helping you stay aware of measurements without constantly watching the display. HOLD function freezes the current display value with a dedicated button, making it easy to record or compare measurements later. Unit button switches between degrees and percent slope, supporting quick conversion for different tasks and standards. Simple, intuitive controls provide reliable operation in field or workshop environments. Compact handheld form factor (as implied by a singlebutton access to key functions) supports onehanded operation and easy portability. Clear visibility of readings with immediate feedback when toggling reminders or units, reducing mistakes and saving time. Compatibility and practicality: designed for common slope and angle measurement tasks where quick access to audible alerts, frozen readings, and unit flexibility improves workflow. 23 use scenarios Site drainage slope installation: enable acoustic reminders to cue when the target slope is approached, use HOLD to freeze the current reading while making adjustments, and switch between degrees or percent slope to match project specifications. Roof pitch verification: quickly toggle between degree and percent slope to meet different building codes, listen for reminders during critical steps, and freeze readings for documentation during inspection. Workshop alignment tasks: measure machine or jig angles, hold the display to capture the value for setup, and convert units as needed to align with manufacturing tolerances. Notes Features described are focused on measurement display control (acoustic reminders, hold, unit switching) to improve accuracy and efficiency in practical applications. No additional specifications beyond the described functions are included.
