• To Power On: Press the OK button briefly. The display will light up.
• To Power Off: Press and hold the C/OFF button for a few seconds until the display turns off. The device will also automatically power off after a period of inactivity to conserve battery.

5. Operating Instructions

The RONGUAN Laser Measure offers multiple measurement modes to suit various needs. The device features a fast response time, completing measurements in 0.3 seconds.

Figure 5.1: Visual representation of the multiple measurement modes supported by the device, including single measurement, continuous measurement, even area measurements, volumetric measurements, cross-hatched line, cosine measurement, Pythagoras measurement, and cumulative additions and subtractions.

5.1 Basic Measurement (Single Measurement)

1. Power on the device. It will typically default to single measurement mode.
2. Point the laser at the target surface.
3. Press the OK button briefly. The measurement will be displayed instantly.

5.2 Continuous Measurement

This mode allows for dynamic measurement as you move the device, displaying real-time distance updates.

1. Press the Mode button until the continuous measurement icon appears on the display.
2. Press the OK button to start continuous measurement.
3. Move the device; the distance will update continuously.
4. Press OK again to stop.

5.3 Cross Laser Projection

The device can project a cross laser line, useful for alignment and leveling tasks. This feature has an effective distance of up to 8 meters.

1. Press the Mode button until the cross laser icon appears.
2. The device will project a horizontal and vertical laser line.
3. To turn off the cross laser, press the Mode button again or the C/OFF button.

5.4 Area and Volume Measurement

These modes allow for quick calculation of areas (length x width) and volumes (length x width x height).

1. Press the Mode button to select Area or Volume mode. The display will prompt for the first dimension.
2. Measure the first dimension (e.g., length) by pointing the laser and pressing OK.
3. The display will then prompt for the next dimension (e.g., width). Measure it.
4. For Volume, measure the third dimension (height).
5. The calculated area or volume will be displayed.

5.5 Pythagorean Theorem Measurement

Use this mode to calculate indirect distances (e.g., height of a building) using two or three measurements.

1. Press the Mode button to select the desired Pythagorean mode (e.g., two-point or three-point).
2. Follow the on-screen prompts to take the necessary measurements (e.g., hypotenuse, base).
3. The device will automatically calculate and display the unknown side.

5.6 Data Storage and Voice Announcements

The system automatically stores up to 50 sets of historical data, allowing for easy review without manual recording. The device also features intimate voice announcements for convenience.
