Product Introduction

LM600A series laser rangefinders can be used in power equipment installation, highway, municipal engineering, forestry survey and design, construction, network planning, communication maintenance and golf.

•  While clearly observing objects, the product can measure the distance of fixed or slow moving objects in a certain range. It has the advantages of high accuracy, short measuring time, direct distance display, low power consumption and auto power off.
•  The laser power is small. The product can measure any target. It is compact and portable and has built-in rechargeable lithium battery.

PowerOn

Rotary Focusing Ring

“+” and “-” on the knob indicate the direction
Users who can’t see close (e.g., farsighted) should rotate in the “+” direction, and users who can’t see far (e.g., nearsighted) should rotate in the “-” direction. Rotate the knob to match eye distance with pupil distance.

Modes

Short press M to switch between different modes. There are 5 modes:

1. M1: Linear distance+ horizontal distance/height + angle
2. M2: Linear distance + compensation distance + flagpole distance + angle
3. M3: Speed measurement mode
4. M4: Length, width, area + angle
5. M5: Length, width, height, volume+ angle

Units and HOLD

• Units
  In M1 or M2 mode, long press M for 3s to switch between units (meter/yard).

• HOLD
  In any mode, long press O for 3s to enter the HOLD mode. The rangefinder will remain turned on. Short press Oto exit the HOLD mode. The rangefinder will shut down after a period of time. To return or clear, users can also short press H

Linear Distance

Measure the target distance, height and angle.
Single measurement: Short press Power Button to take a measurement. Continuous measurement: Long press Power Button to scan the laser across an area and get continuously updated range readings.

Flagpole Lock

When measuring overlapping targets, long press Power Button to display the distance of the nearest target. For example, if it is not clear whether the measured target is the flag or the forest behind it, the product with the flagpole lock function will lock on the nearest target, the flagpole.

Golf Measurement

Long press Power Button to display the golf trajectory compensation distance, height and actual distance.

• Uphill
  

• Downhill

Height and Horizontal Distance

Short/long press Power Button to display the relative height and horizontal distance of the observer to the target.

Speed Measurement

Press and hold Power Button and aim at the moving target. The product will calculate the target speed in real time and display it on the LCD.

Area Measurement

In M4 mode, press Power Button to measure the length and width of the target. The product will automatically calculate the area.

Volume Measurement

In M5 mode, press Power Button to measure the length, width and height of the target. The product will automatically calculate the volume.

Cautions

The product emits an invisible and harmless infrared pulse laser which is then reflected back to the optical receiver on the product from the target. By measuring how long it takes each pulse laser to travel from the rangefinder to the target and back, the product system uses a precise charging circuit to calculate the measured distance in real time. The maximum measurement range of the product depends on the target’s reflectivity, color, surface finish, size, and actual shape.
The following factors can ensure optimal range and accuracy:

• Sunny weather
• Bright color targets
• Targets with a bright appearance
• No impurities in the air
• Targets with high reflective surfaces

The following factors cannot ensure optimal range and accuracy:

• Black targets
• Snow, rain or fog
• Targets with diffuse surfaces
• Small or micro targets
• Targets to be measured through glass
• Moving targets
• Strong light/sunlight
• When the battery status is  , please charge the battery immediately.
• Do not touch the lens surface to protect the film layer.
• Do not disassemble the product. If it is damaged, send it to specialized departments for maintenance.
• Please wipe the lens gently with a cleaning cloth. Do not wipe with other objects.
• Avoid collision or heavy pressure when carrying.
• Do not bake or corrode the product.
• Store the product in a dry, cool and ventilated place, away from direct sunlight, dust and sudden temperature changes.
• Do not direct the product at the sun or strong light source.
