How can I monitor or calibrate my Disto?
Measure an easily accessible distance of 2m to 10m with a distance measuring instrument approved by your national bureau of standards. Make 10 measurements over the same distance with the Leica DISTO. Determine the deviation of your measurements from the actual distance and calculate the standard deviation from the results. Record the value and set the time for the next series of measurements. Repeat these check measurements regularly, especially before and after important measuring tasks. Mark the Leica DISTO with aninspected sticker and protocol the entire monitoring process. Your Leica DISTO meets the specified accuracy, if the standard deviation is equal to or less than the value stated as the typical standard deviation. A Leica DISTO checked on the test distance works with the specified accuracy over the entire specified measuring and temperature ranges.
