UNI-T LM2000 Laser Rangefinder User Manual - Initial Operation and Settings Eyepiece

Power on/off
Press the power button UNI-T LM2000 Laser Rangefinder User Manual - Power button to turn the product on. If there is no operation within 16 seconds, the rangefinder will automatically shut down.

Angle Calibration
The rangefinder has been calibrated before leaving the factory. If the measurement data is inaccurate in the two point distance measurement mode, long press the power button UNI-T LM2000 Laser Rangefinder User Manual - Power button in the shutdown state to enter the calibration interface. The interface will display “ANGLE CAL”. Keep the product in a stationary state, and the calibration will be completed after a few seconds. If the calibration cannot be completed for a long time, the rangefinder will automatically shut down in about 1 minute, that is, the calibration has failed. UNI-T LM2000

UNI-T LM2000 Laser Rangefinder User Manual - IF the calibration failsIf the calibration fails, the factory calibration will continue to be used when restarting.

VII. Operating Instructions

Short press O to switch measurement modes.

  • Before measuring, please adjust the eyepiece knob to make the target clear. If the target reflection is weak or out of the measuring range during measurement, “—” will be displayed. UNI-T LM2000
  • The range of the rangefinder is related to the nature of the measured target, the tilt angle of the target surface, and the weather visibility. Generally speaking, if the target surface is smooth, bright, large and perpendicular to the beam, and the weather is cloudy and fogless, the longer the range, and vice versa.

VIII. Flagpole Lock Mode (Close Range Priority)

Distance + Tilt Angle
This mode is mainly used to measure the distance of small objects, and adopts the principle of close range priority. Short press Oto switch to (E) the flagpole lock mode. Aim the aiming dot at the measured object B, and then short press(!) to measure the distance from point A to point B.

Cautions

  1. Do not touch the lens surface with fingers to avoid damaging the film on the surface.
  2. The rangefinder is precisely adjusted by the instrument, so please do not disassemble it randomly. If the product is damaged, send it to a professional maintenance department for repair. UNI-T LM2000
  3. Avoid direct laser exposure for a long lime to prevent burns to the skin.
  4. When the lens is contaminated, please gently wipe it with a soft cloth. Do not wipe it with other objects; otherwise the film on the lens surface may be damaged.
  5. Do not bump, press, bake or corrode the product.
  6. The product should be stored in a dry, cool, and ventilated place to avoid direct sunlight, dust and sudden temperature changes.
  7. Measurement in rainy and foggy weather will affect the round-trip time of the laser, which may increase the measurement error, and even cause the measurement value to be wrong in severe cases. UNI-T LM2000
