The UNI-T LM320E is a compact digital angle meter designed for checking angles, slopes and alignment during installation work.
It combines digital angle measurement with two projected laser lines.
This allows the user to measure the angle at the instrument and extend a visible reference toward another position.
The LM320E may be useful for:
Machinery installation
Steel fabrication
Pipe and bracket installation
Cabinet installation
Shelving work
Building maintenance
Renovation
Equipment levelling
Slope checking
Angle transfer
For contractors and maintenance teams in Malaysia, the LM320E is more versatile than a basic digital angle meter when a visible reference line is also required.
What Can the UNI-T LM320E Measure?
The LM320E has a 4 × 90° angle-measurement range.
It can be used to check whether a surface or component is:
Horizontal
Vertical
Inclined
Sloping upward
Sloping downward
Positioned at a specified angle
The measurement result can be displayed in:
Degrees
Percentage
mm/m
in/ft
The correct unit depends on the drawing, installation requirement or working method used by the customer.
Why Does the LM320E Have Two Laser Lines?
A standard digital angle meter measures the surface that directly contacts the instrument.
The LM320E also projects two laser lines to extend the reference beyond its compact body.
This may help when:
Aligning brackets
Positioning shelves
Transferring an angle
Installing cabinets
Checking pipe direction
Comparing installation points
Following a reference across a wider area
The laser lines do not independently determine the angle.
The angle value comes from the internal angle sensor, while the lasers provide a visible positioning reference.
The user should therefore check both the digital reading and the physical placement of the instrument.
Absolute Angle Measurement
Absolute angle measurement shows the instrument’s angle according to its normal reference.
This mode is suitable when the user wants to check:
Whether a surface is level
Whether a frame is vertical
The slope of a pipe
The inclination of a machine component
The installation angle of a bracket
The contact surface should be clean, stable and sufficiently flat before the reading is accepted.
Relative Angle Measurement
Relative measurement allows the user to establish a selected surface as the zero reference.
The LM320E can then show the difference between that reference and another surface.
This function may be useful for:
Copying an existing angle
Comparing two components
Installing repeated brackets
Checking whether two surfaces have the same slope
Working from a reference that is not perfectly horizontal
Relative mode is particularly helpful when the required installation angle is based on an existing structure rather than the true horizontal level.
Magnetic Mounting on Metal Surfaces
The LM320E has magnetic mounting surfaces at the bottom and rear.
It can attach to suitable steel surfaces during measurement.
Possible applications include:
Steel frames
Machine bodies
Metal brackets
Fabricated components
Large steel pipes
Industrial equipment
Workshop structures
Magnetic mounting can help keep the instrument stable while the user adjusts the component.
However, the magnetic base does not correct an unsuitable measurement surface.
Rust, welding residue, metal particles, dirt and uneven surfaces can prevent the LM320E from sitting correctly.
The contact surface and magnetic base should be inspected before every important measurement.
Using the Rotating Colour Display
The LM320E has an illuminated display that rotates according to the instrument’s position.
This can make the result easier to read when the instrument is:
Placed horizontally
Mounted vertically
Attached to the side of equipment
Positioned upside down
Used in a restricted area
The display is useful for workshops, indoor installations and maintenance locations with limited lighting.
The user should still confirm that the selected measurement unit and reference mode are correct.

Machinery Installation Applications
The LM320E may assist maintenance teams when checking the inclination of:
Machine frames
Motor supports
Equipment bases
Adjustment plates
Metal guards
Mounted components
Its magnetic mounting can be convenient when working on steel machinery.
However, a digital angle meter does not replace a precision shaft-alignment system or machinery manufacturer’s approved alignment procedure.
If the job involves coupling alignment, shaft alignment or very small positional tolerances, dedicated alignment equipment may be required.
Steel Fabrication Applications
Fabricators may use the LM320E to check:
Frame angles
Welded brackets
Steel supports
Fabricated sections
Inclined members
Temporary positioning before welding
Several readings should be taken before final welding or fastening.
Heat distortion, welding movement and irregular steel surfaces can change the final position after the initial measurement.
Pipe and Bracket Installation
The LM320E can help check the slope of:
Metal pipes
Pipe supports
Cable trays
Drainage components
Mounting brackets
Inclined channels
Before adjustment, the installer should confirm the required slope from the project drawing or engineering specification.
A displayed percentage or mm/m result should not be accepted until the user confirms that the correct measurement unit has been selected.
Cabinet and Shelving Installation
The dual laser lines can assist when installing:
Cabinets
Shelves
Wall brackets
Storage systems
Interior fittings
Display fixtures
The digital angle reading helps the user compare multiple installation points.
For long-distance room layout or full-wall horizontal projection, a dedicated line laser may be more suitable.
Is the LM320E a Laser Level?
The LM320E is primarily a digital angle meter with two laser reference lines.
It should not automatically be treated as a replacement for a professional laser level.
Choose the LM320E when the main requirement is:
Measuring an angle
Checking a slope
Comparing two surfaces
Transferring an angle
Mounting the instrument on steel
Extending a short visible reference
Consider a dedicated line laser or rotary laser when the main requirement is:
Projecting long horizontal lines
Projecting full-room vertical lines
Setting out construction work
Levelling across a large area
Working outdoors with a laser receiver
Establishing elevation over a longer distance
Choosing according to the actual application is more important than choosing according to the number of laser lines.
Can the LM320E Replace a Spirit Level?
The LM320E can perform many general levelling and slope-checking tasks, but it does not make every spirit level unnecessary.
A longer spirit level may provide better physical contact across a wide or irregular surface.
The LM320E is more useful when the customer requires:
A numerical angle result
Several measurement units
Relative-angle measurement
Magnetic attachment
A compact instrument
Laser reference lines
Some users may benefit from carrying both instruments.
The spirit level provides a longer physical reference, while the LM320E provides a digital angle value and laser indication.
How to Take a More Repeatable Measurement
Before using the LM320E:
1. Clean the measurement surface.
2. Remove metal particles from the magnetic base.
3. Check that the instrument can sit flat.
4. Select the correct measurement unit.
5. Confirm whether absolute or relative mode is required.
6. Allow the displayed value to stabilise.
7. Repeat the reading from the same position.
8. Compare the result with a known reference when necessary.
9. Mark the exact measurement position for repeated work.
10. Avoid using the laser line alone as the angle result.
If small changes in placement produce large differences, the surface or measurement method should be evaluated before continuing.
Laser Safety During Use
The LM320E uses a Class 2 laser.
Users should not stare directly into the laser beam.
The beam should not be intentionally directed toward:
A person’s eyes
Passing workers
Drivers
Reflective surfaces
Aircraft
Public areas without proper control
Extra care is required when working around polished metal, glass or mirrors because the beam may be reflected.
The laser should be switched off when it is not needed.
When May the LM320E Be Unsuitable?
Another instrument may be more appropriate when:
The required accuracy is tighter than the LM320E specification
The surface is too narrow or uneven
The measurement area is affected by vibration
Precision machinery alignment is required
Long-distance construction levelling is required
Outdoor laser visibility is essential
A laser receiver must be used
The installation follows a specialised engineering standard
A stable display does not automatically confirm that the selected instrument is suitable for the required tolerance.
