Setup
Charging the Device
The eOUTIL DL905 comes with a built-in rechargeable 400mAh Lithium Polymer battery. Before first use, ensure the device is fully charged.
- Locate the USB-C charging port on the side of the device.
- Connect the provided USB-C cable to the device and the other end to a standard USB power adapter (not included) or a computer USB port.
- The charging indicator on the display will show charging status. A full charge typically takes a few hours.
- Disconnect the cable once charging is complete.

Initial Power On
Press and hold the Power / Data Hold button (11) for approximately 2 seconds to turn on the device. The backlit LCD display will illuminate.
Operating Instructions
Power On/Off
- To power on, press and hold the Power / Data Hold button (11) for 2 seconds.
- To power off, press and hold the Power / Data Hold button (11) for 2 seconds. The device will also automatically power off after a period of inactivity to conserve battery.
Basic Angle Measurement
Place the base of the device firmly on the surface you wish to measure. The angle will be displayed on the LCD screen.

Absolute and Relative Measurement Modes
- Absolute Measurement Mode: This mode measures the angle relative to a true horizontal plane (0°). This is the default mode upon power-on.
- Relative Measurement Mode: To measure the angle difference between two surfaces, place the device on the first surface and press the 0-90°/0-180° Range Switch & ZERO Function button (13) to set the current position as 0°. Then, move the device to the second surface; the display will show the relative angle.
Zeroing the Device
To set the current surface as the reference 0° (relative measurement), place the device on the desired reference surface and short press the 0-90°/0-180° Range Switch & ZERO Function button (13). The display will show '0.00°'.
Using the Laser Function
The device features three laser line modes: horizontal, vertical, and cross line.
- Press the Laser ON/OFF button (14) to activate the laser.
- Each subsequent short press of the Laser ON/OFF button (14) will cycle through the laser modes: Horizontal Line > Vertical Line > Cross Line > Laser Off.
- Position the device to project the desired laser line onto your working surface.

Hold Function
To freeze the current reading on the display, short press the Power / Data Hold button (11) while the device is on. The 'HOLD' indicator (2) will appear. Press it again to release the hold function.
Unit Conversion
Short press the Mode Setting Unit & Audible Buzzer ON/OFF button (12) to cycle through different measurement units: degrees (°), mm/m, IN/FT, and percentage (%).
Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, ensure the battery is partially charged.
