 | Continuous measurement can help identify maximum and minimum distances while the device is moved. Confirm the mode behavior and display sequence for the selected model. |
 |
Area mode guides the user through width and length measurements, then calculates the resulting area. |
Volume mode guides the user through width, length, and height measurements, then calculates the resulting volume. |
 | Indirect measurement uses the Pythagorean theorem to calculate a height from guided distance measurements. Follow the on-screen sequence and confirm the applicable mode for the model. |
Use the unit settings to select the measurement format required for the intended market. Confirm the published unit list for the selected model. |
Addition and subtraction can be applied to successive measurements to calculate a running result.
The backlit display supports reading in changing ambient light. Confirm display behavior and battery test conditions for the selected configuration.
