Getting Started
1. Battery Installation
- Locate the battery compartment cover on the back of the device.
- Use the provided mini screwdriver to open the battery compartment.
- Insert two AAA batteries, ensuring correct polarity (+/-).
- Close the battery compartment cover and secure it with the screw.
2. Power On/Off
- Press the ON/OFF button (labeled with a power symbol) to turn the device on.
- Press and hold the ON/OFF button to turn the device off.
- The device will automatically power off after 3 minutes of inactivity to conserve battery life.
Operating Instructions
Absolute and Relative Measurement Modes
The angle finder supports two measurement modes: Absolute (ABS) and Relative (REL).
- Absolute Measurement (ABS): This is the default mode. It measures the angle relative to a true horizontal surface (0°).
- Relative Measurement (REL): To enter Relative mode, short-press the ZERO button. In this mode, the current position is set as the new 0° reference, allowing you to measure the angle difference from that specific point. Short-press ZERO again to return to Absolute mode.

Unit Switching
The device can display measurements in four different units: degrees (°), percentage (%), mm/m, and in/ft.
- Press the W button (labeled 'W' or 'MODE') to cycle through the available measurement units.

Data Hold Function
To freeze the current measurement on the display:
- Press the H button (labeled 'H' or 'HOLD'). The 'H' icon will appear on the screen.
- Press the H button again to release the hold and resume live measurement.
Using the Magnetic Base
The strong magnetic base allows for hands-free operation on ferrous materials.
- Simply place the magnetic base firmly against the metal surface you wish to measure. The V-slot design ensures stable attachment even on rounded pipes or shafts.
- Ensure the surface is clean and free of debris for optimal magnetic grip.

Flip LCD VA Screen
The display screen can be adjusted for better visibility.
- Gently lift the LCD screen to your desired viewing angle (0°, 30°, 60°, or 90°). This feature is particularly useful when working in tight spaces or at awkward angles.

Built-in Bubble Level
For quick visual checks or when batteries are not available, the integrated bubble level can be used.
- Observe the bubble in the vial on the top of the device to determine if a surface is level or plumb.

Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the angle finder in a dry place, away from direct sunlight and extreme temperatures. Remove batteries if the device will not be used for an extended period.
- Battery Replacement: Replace batteries when the low battery indicator appears on the display. Always use new AAA batteries.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low or dead batteries; incorrect battery installation. | Replace batteries with new AAA batteries, ensuring correct polarity. |
| Inaccurate readings. | Device not properly zeroed; magnetic interference; surface not flat. | Ensure the device is zeroed on a known flat surface. Avoid strong magnetic fields. Ensure the measurement surface is stable. |
| Display shows "Err". | Measurement range exceeded or internal error. | Ensure the angle is within the 2x180° or 4x90° range. Try turning the device off and on again. If the problem persists, contact customer support. |
