| Product Description: |
|
The Opti-Logic LH-series Laser Rangefinder/Hypsometer height measurement system combines a pulsed laser rangefinder and a vertical angle sensor in a lightweight, easy-to-use package. The hand-held rangefinder is capable of measuring distances to non - cooperative targets up to 1000 yards away (Model 1000LH), depending on target size and reflectivity. Incorporating an internal electronic tilt sensor, the Laser Rangefinder/Hypsometer makes vertical angle measurements with better than 1 degree resolution to remotely determine object heights. Applications of the hypsometer measurement system include tree height measurements, construction, utilities, architectural measurements, landscaping, real estate appraisal, and much more. The system is ideal for applications where surveying quality measurements are not required and higher instrument cost is not justifiable. This product is designed for years of trouble-free operation and is proudly Made in the USA.

| Basic Operations: |
A. Hold the instrument an inch or two from your eye and aim at the object through the viewfinder.
B. Press and hold the "Range" button. A "Red Dot" will appear in the viewfinder. Place the Red Dot on the target.
C. Release the button and maintain aim on the target momentarily. The "clicking" sounds indicate that the laser is hitting the target. Like a Geiger counter, stronger signals produce more rapid clicking. The laser does not fire until the button is RELEASED.
D. Read the distance after the audible tone is heard and the Red Dot turns off. |

Distance Measuring w/ Time-of-Flight Rangefinders
|
The Opti-Logic Laser Rangefinder emits invisible, eye-safe pulses of infrared light. Distances are determined by reflecting the laser beam off an object and measuring the round-trip time-of-flight of the laser beam to and from the object. The laser beam emitted by the Rangefinder is in the form of a vertical stripe of invisible light, which enhances the Rangefinder's ability to hit thin vertical targets. The Opti-Logic Laser Rangefinder incorporates a unique "Lock and Load" feature that simplifies the task of hitting targets in the presence of background objects. Simply depress the "Range" button and aim the Rangefinder using the Red Dot aiming aid in the viewfinder. The laser is fired AFTER the button is released, which provides time to properly aim the Rangefinder and minimizes the chance of hitting unintended objects. When the Rangefinder laser beam hits

Mode 1: Line-of-Sight Distance. Press the range button to activate the Red Dot aiming device and place the Red Dot on your target. Release the button and wait for the beep. When the beep sounds, read the distance in the external LCD.
|
Mode 2: Tilt-Compensated Horizontal Distance. Press the range button to activate the Red Dot aiming device. Put the Red Dot on your target. Release the button and wait for a single beep followed by a double beep. DO NOT MOVE THE UNIT UNTIL THE SECOND BEEP SOUNDS: after the unit takes its distance measurement, it must take an angle measurement. When the double beep sounds, read the distance in the LCD.
|
Mode 3: Height Measurement. This mode requires three measurements: 1) Center, 2) Top, and 3) Bottom in that order. The first measurement to the object being measured can be to any point presenting a clear line-of-sight. Press the button and "CEN" appears in the LCD. Aim the Red Dot at the Target, release the button and wait for the beep. The LCD will then display "TOP". Aim the unit at the top of the object to be measured; press and release the button, wait for the beep. The LCD will then display "BOT". Aim the unit at the bottom of the object to be measured; press and release the button; wait for a double beep. The LDC will then display the height measurement of the object. It is not necessary to be able to see either the top or the bottom of the object being measured, since the TOP and BOT measurements are angle measurements, not the distance measurements
|
Mode 4: Angle Measurement. To determine the angle or slope, press and hold the range button, place the Red Dot on the point to be measured, release the button, wait for the beep to sound before lowering the unit, and read the angle (deg icon) or percent grade
(no icon) in the LCD.

General Care
|
The Opti-Logic Laser Rangefinder/Hypsometer is a sophisticated electronic and optical instrument, built to withstand a reasonable amount of handling with the same amount of care as any other optical or electronic device, such as a camera, binoculars, riflescope, telescope, etc. Keeping the lens clean will insure optimum operation and performance. Use a soft, clean non - abrasive cloth to clean the lenses. Cotton swabs work well. Never use paper or other a brasive materials. Dampen a cloth with either a very mild soap solution or clean water. Gently rub the lenses with a dampened cloth. DO NOT SCRUB THE LENSES. After cleaning the lenses, gently wipe the lenses off with a soft dry cloth. NEVER use petroleum products or chemicals to clean the lenses or any parts. Use the same procedure to clean the exterior. Although the Opti-Logic Laser Rangefinder/Hypsometer has beendesigned to withstand normal outdoor use, some common sense precautions should be observed. NEVER subject your laser rangefinder to shock, high temperature, or harmful chemicals or gases. If the Rangefinder is not going to be used for long periods of time, remove the battery and store in a cool, dry place. DO NOT use chemicals or solvents to clean the Rangefinder. Chemicals, insect repellents and solvents can damage the plastic housing and lenses of the Rangefinder.

Low Battery Indicator
|
When the battery voltage becomes too low, the instrument may act erratically or cease to function. The low battery indicator will appear in the display before this occurs. The battery should be replaced as soon as possible after the indicator is displayed.

| Errors / Troubleshooting |
a target, a clicking sound is produced to provide audible feedback to make it easier to home in on your target. The rate of clicking is faster for brighter, closer objects, much like a Geiger counter. To improve the accuracy of the instrument, an onboard computer averages several readings from the object. After the Rangefinder has received enough information, the audible clicking and Red Dot turn off and the distance is shown in the display. A tone or "beep" will sound when the distance is displayed. The maximum distance measurable by any laser rangefinder is determined by several factors including the size, shape, reflectivity, and orientation of the object as well as atmospheric conditions. Color and surface finish of the target also affect the reflectivity and therefore can influence the range as well. A good quality target is a non-gloss object that is light in color and has enough surface area for the laser beam to efficiently reflect back to the Rangefinder. Vertical objects tend to make better targets than horizontal ones. White objects tend to range farther than black objects. Target surfaces that are perpendicular to the laser beam are better than surfaces tilted away from the Rangefinder. Targets made of "retroreflectors" provide the greatest range capability. Retroreflectors are made of special materials designed to reflect light back toward the light source, for example, stop signs, street signs, license plates, and specially made Opti-Logic reflectors. Contrary to expectation, extremely glossy surfaces like windows and mirrors do not make good targets, because they tend to reflect light away from the instrument.

Mode Selection
|
|
The Opti-Logic Rangefinder/Hypsometer provides user-selectable display units and four operational modes allowing the user to (1) determine range to an object, (2) determine horizontal range to an object even when the aim point is at an angle, (3) determine the height of an object, and (4) determine the vertical angle to an object. In Modes 1, 2, and 3, the user may select units of feet, yards, or meters. To enable the mode selection process, hold the firing button down for approximately 6-8 seconds until a double - beep is heard. Immediately release the button, then repeatedly press and release the button to scroll through menu options: Mode 1: Meters (Reflective), Meters (Non-reflective), Feet (Reflective), Feet (Non-reflective), Yards (Reflective), Yards (Non-reflective); Mode 2: Meters, Feet, Yards; Mode 3: Meters, Feet, Yards; Mode 4: Degrees, % Grade (with no icon). About 5 seconds after the desired menu option is selected, the instrument will beep, return to operational mode, AND IMMEDIATELY TAKE A READING.

A. If the unit 'locks up', remove the battery for several seconds and press the range button with no battery installed, then reinstall the battery. If problem continues, try a new battery.
B. If the Rangefinder displays an incorrect distance, make sure that the "Red Dot" in the viewfinder is hitting the object. Try aiming the Rangefinder at a nearby reflective target such as a street sign or automobile license plate to verify alignment.
C. If the Rangefinder shows a distance of "0", the Rangefinder is hitting an object at a distance that is less than the minimum distance. Try aiming the Rangefinder at a more distant object to verify operation.
D. Make sure the battery terminals are in contact with the metal battery clips when replacing old battery.
