This document serves as the user manual for the UNI-T LM320A and LM320B digital angle meters. It provides comprehensive guidance on the features and operation of these precision measuring instruments.
Key Features and Operation
The LM320A/LM320B digital angle meters are designed for accurate angle measurement. Key operational aspects include:
- Power Management: Simple power on/off functions via a dedicated button.
- Laser Functionality (LM320B): The LM320B model features side lasers that can be activated individually or simultaneously for enhanced visibility and alignment.
- Angle Measurement: Place the device on an inclined surface to obtain the angle relative to the horizontal plane.
- Relative and Absolute Modes: Switch between relative (REF) and absolute (ABS) measurement modes to set zero points or measure absolute angles.
- Calibration: A straightforward calibration process ensures accuracy by setting the device against a flat surface.
- Data Hold: Freeze the current measurement reading for easy recording.
- Unit Conversion: Easily convert between different measurement units such as degrees (°), millimeters per meter (mm/m), and percentage (%).
