Setup
1. Battery Installation:
- Locate the battery compartment cover on the back of the device.
- Slide the cover open.
- Insert two AAA batteries (not included) according to the polarity indicators (+/-) inside the compartment.
- Close the battery compartment cover securely.
2. Power On/Off:
- To power on, press the READ button.
- To power off, press and hold the OFF/CLEAR button for a few seconds, or the device will automatically power off after 150 seconds of inactivity.
Operating Instructions
1. Basic Single Distance Measurement:
- Point the device at the target.
- Press the READ button once to activate the laser.
- Press the READ button again to take a measurement. The distance will be displayed on the screen.
2. Continuous Measurement (Tracking):
- Press the Function button until the continuous measurement icon appears on the display.
- Press the READ button. The device will continuously measure and display the current distance, as well as minimum and maximum values.
- Press OFF/CLEAR to stop continuous measurement.
3. Area Measurement:
- Press the Function button until the area measurement icon appears.
- Press READ to measure the first side (length).
- Press READ again to measure the second side (width).
- The device will automatically calculate and display the area.
4. Volume Measurement:
- Press the Function button until the volume measurement icon appears.
- Press READ to measure length, then width, then height.
- The device will automatically calculate and display the volume.
5. Pythagorean Measurement:
This function allows indirect measurement of height or distance using the Pythagorean theorem.
- Press the Function button until the Pythagorean measurement icon appears (e.g., for two-point or three-point Pythagorean).
- Follow the on-screen prompts to measure the required sides (hypotenuse, base).
- The device will calculate and display the unknown side.
6. Addition and Subtraction:
- Take a measurement.
- Press the +/- button to select addition or subtraction mode.
- Take another measurement. The result will be added or subtracted from the previous measurement.
7. Unit Conversion:
- Press the Unit button to cycle through available units: meters (m), inches (in), and feet (ft).
8. Historical Data Storage:
- The device can store up to 30 sets of measurement data.
- To recall historical data, press the Memory button (often indicated by a folder icon). Use the arrow buttons (if available, or +/-) to navigate through stored measurements.
Maintenance
- Cleaning: Use a soft, damp cloth to clean the device surface. Do not use organic solvents or abrasive cleaning agents.
- Storage: If the device will not be used for a long time, remove the batteries and store it in a cool, dry place.
- Lens Care: Keep the laser emitter and receiver lenses clean. Use a soft cloth specifically designed for optical lenses to avoid scratching.
