Repeat these tests at frequent and
regular intervals, also before and
after important measuring jobs.
Affix an adhesive label on the DISTO
for accuracy tests of measuring
equipment and keep a detailed
record of the test procedure.
Your DISTO meets the specified
accuracy if standard deviation
remains smaller or equal to the
typical specified value.
A DISTO whose measuring accuracy
has been tested over a test distance
works within the specified tolerance
over the entire distance and
temperature range specified in the
manual.
Please note the technical data and
the description of measuring
accuracy in the manual
