Unit "cannot measure" at any distance

Target cannot be measured at any distance. I have put a new battery in the unit and problem remains. The lens is not obstructed. The unit worked great for about four months after I got it and then it just quit measuring.

    Laser finder worked perfectly for four months, then it just stopped giving distance, meters to yards button works. Press power button and three dashes are displayed.

    Same thing... Used it very little last year. Then I just got it out this year, thought the battery was the problem, replaced it, and no measuring distance...

I compete in 3d archery so I bought a new rangefinder 2 days ago and it reads 19.2 yards at exactly 20 yards is there a way to adjust it to read properly?


Page 5 of the manual states: RANGING ACCURACY The ranging accuracy of the Scoutâ„¢1000 is plus or minus one yard / meter under most circumstances. The maximum range of the instrument depends on the reflectivity of the target. The maximum distance for most objects is 650 yards / 594 meters while for highly reflective objects the maximum is 1000 yards / 914 meters. Note: You will get both longer and shorter maximum distances depending on the reflective properties of the particular target and the environmental conditions at the time the distance of an object is being measured. The color, surface finish, size and shape of the target all affect reflectivity and range. The brighter the color, the longer the range. White is highly reflective, for example, and allows longer ranges than the color black, which is the least reflective color. A shiny finish provides more range than a dull one. A small target is more difficult to range than a larger target. The angle to the target also has an effect. Shooting to a target at a 90 degree angle (where the target surface is perpendicular to the flight path of the emitted energy pulses) provides good range while a steep angle on the other hand, provides limited ranging. In addition, lighting conditions (e.g. the amount of sunlight) will affect the ranging capabilities of the unit. The less light (e.g. overcast skies) the farther the unit's maximum range will be. Conversely, very sunny days will decrease the unit's maximum range.

The difference you are experiencing (20-19.2=.8 yards) is within the device ranging accuracy of 1 yard, and is in fact an error of only 4%. That is pretty accurate

In case you have lost your manual, you can download from here:

Good luck with your device.

Does not measure distance


Put in new batteries, clean lens, and calibrate. If this does not work, type " Leica Disto A6 Laser Distance Meter user manual " into computer search engine. It will bring up sites for manual.

Kodak carousel 760h projector


The auto-focus system in Kodak slide projectors is really an auto-measurement system: One set manually, the system is supposed to maintain that distance on all subsequent slides. Correct orientation of the slides is that they are all placed in the slide tray in the SAME direction (the matte side of the transparency facing toward the screen). The measurement is from the FRONT of the slide transparency to the BACK of the projection lens. REPAIR calibration of the system requires 2 special tools: a RANGE SLIDE and a TARGET SLIDE. These tool slides and the calibration procedure SHOULD be available from: www.micro-tools.com They purchased all remaining repair parts from Kodak when Kodak stopped supporting slide projectors. Good Luck !! Jim

are you sure about your instrument setting? you try press button "MRS1" or "MRS2", hold around 1 second n 1/5. Then at monitor come out "Target","Const","Mode","AVE" and "Rec mode". At "Target", u choose "prism". Good Luck.

Error Bosch DLR130 distance measurer


Same problem Err and --- on display. The front lens had become misaligned. Take off front rubber boot, clean lens and replace lens exactly in glue pattern on unit with rounded side facing out. Then holding unit with seated lens upright push rubber boot slowly back on. Very hard at first but push as much in by hand then use a narrow blunt point like the back of a screwdriver handle to press around the edge working it in with slow continuous pressure a quarter inch at a time. It will reseat just take your time and work the high spots. This time was not the batteries, works like new.

Unit is measuring cadence and heart rate, but is not measuring speed, distance or ride time.


Check to make sure your speed/ distance sensor is in alignment with your wheel magnet. If it is then check the battery in the sensor.

Speed and distance are on a different sensor than the cadence.
