Attention: If the instrument is not able to
bring the length standard calibration within
tolerance after several cycles (i.e., if there is
a continuous Fail), reset the instrument, and
try the length standard procedure again.
BEFORE YOU RESET, REMOVE THE METAL
LENGTH STANDARD FROM THE COMB
TRACK.
3.5.2 Length Standard Check
The Length Standard Check screen is used by Service Technicians to
give the repeatability of the length standard value. This measures, but
does not change, the total travel.
3.5.3 Length Standard Value
The value for the metal length standard is listed on the standard that is
provided with the instrument. Do not use a metal length standard other
than the one provided with the instrument. If, for some reason, a new
metal length standard is required, this menu item is used by Service
Technicians to enter the new value.
