How to Use It

1. Insert the Batteries

  • Open the battery cover on the back.
  • Insert 2 × AAA batteries (included) with correct polarity.
  • Close the battery compartment.

 2. Power On the Device

  • Press the Power/Measure button (usually marked with a red or laser symbol).
  • The LCD screen will light up and display the default measurement mode.

3. Select Measurement Mode

  • Press the Mode/Function button to cycle through:
  •  Single Distance Measurement
  •  Area Calculation (length × width)
  • Volume Calculation (length × width × height)
  • Indirect Measurement (Pythagorean 2-point or 3-point)
  •  Continuous/Real-Time Measurement

4. Set the Reference Point (Front/Back)

  • Use the Reference button to choose whether measurement starts from the front or rear edge of the device.
  • Useful for tight spaces or corner measurements.

5. Take a Measurement

  • Aim the laser at the target surface (make sure it’s solid and clearly visible).
  • Hold the device steady and press the Measure button.
  • The measured value will appear on the backlit LCD display.

6. Use Additional Functions (Optional)

  •  Add or Subtract Measurements: Useful for cumulative distances.
  •  Unit Conversion: Switch between meters, feet, or inches using the unit change button.
  • Continuous Mode: Enables tracking moving targets or checking minimum/maximum distances.

7. Power Off or Auto Shut-Off

  • The device will automatically power off after a few minutes of inactivity.
  • Or press and hold the Power button to shut down manually.

Maintenance : 

1. Keep the Device Clean

  • Use a soft, dry microfiber cloth to wipe the exterior and screen regularly.
  • For the laser lens, use a lens cleaning cloth or blower brush—avoid rough or wet cloths that could scratch it.
  • Never use harsh chemicals, solvents, or abrasives.

2. Protect from Moisture & Dust

  • Although it has IP54 protection, avoid:
                        Prolonged exposure to heavy rain or wet environments.
                        Using it in very dusty or dirty areas without proper casing.

  • Always store the device in its protective case when not in use.

3. Battery Care

  • Use only high-quality AAA batteries (alkaline recommended).
  • Remove the batteries if:
                         The device will not be used for more than a month.
                         You notice leakage, corrosion, or low power.

  • Replace batteries when the low battery indicator appears to avoid inaccurate readings.

4. Calibration Check (Optional)

  • Periodically verify the meter’s accuracy by comparing it to a known fixed distance (e.g., 1 m or 5 m).
  • If you notice consistent deviation beyond ±3 mm, contact customer support or service center for calibration.

5. Avoid Physical Shock

The JCB LDM-30 is drop-resistant, but :

  • Avoid intentional dropping or knocking it against hard surfaces.
  • Use the ergonomic anti-slip grip to hold it securely during use.

6. Storage Guidelines

  • Store in a dry, cool place away from direct sunlight.
  • Keep away from magnetic fields or strong heat sources (e.g., heaters, dashboards in hot vehicles).
  • Always use the provided case or pouch during transport.

7. Software or Display Malfunctions

If the display flickers, freezes, or misreads :

  • Remove batteries for 30 seconds, then reinsert.
  • If the issue persists, reset the device (check user manual for instructions).
  • Contact JCB customer service if required.
