LCD Display: 2-inch screen with backlight for clear visibility of measurements and settings.
Measurement Button (MEAS): Initiates measurements.
Function Buttons: For selecting measurement modes (distance, area, volume, Pythagorean, etc.).
Unit Button (UNIT): Changes measurement units (m/ft/in/ft+in).
Reference Point Button: Switches between front and rear reference points for measurement.
Clear/Off Button (CLEAR/OFF): Clears current measurement or powers off the device.

Setup

Battery Installation

The device requires two 1.5V AAA alkaline batteries. Ensure correct polarity when inserting the batteries.

Open the battery compartment cover on the back of the device.
Insert two AAA batteries, matching the positive (+) and negative (-) terminals as indicated.
Close the battery compartment cover securely.

Power On/Off

To power on, press the MEAS button.
To power off, press and hold the CLEAR/OFF button for a few seconds, or the device will automatically shut off after 180 seconds of inactivity to conserve energy.

Operating Instructions

Basic Distance Measurement

For a single distance measurement:

Point the laser at the target.
Press the MEAS button once. The measurement will be displayed on the screen within 0.5 seconds.

Measurement Modes

The MiLESEEY D5 offers various measurement functions:

Continuous Measurement: For tracking distances as you move the device.
Area Measurement: Calculates the area of a surface (length x width).
Volume Measurement: Calculates the volume of a space (length x width x height).
Pythagorean Method (2-point and 3-point): Indirect measurement for heights or distances where direct measurement is not possible.
Addition/Subtraction: Add or subtract measurements.
Auto Level: Automatically calculates horizontal distance.
Auto Height: Automatically calculates vertical height.

Illustrations of various measurement modes: Distance, Addition/Subtraction, Area, Volume, 2-point Pythagorean, and 3-point Pythagorean. — Image: Visual guide to the different measurement modes available on the device, including direct distance, area, volume, and Pythagorean calculations.
