6.1 High-Speed Guide Rollers
DXN guide roller assemblies are rated 2000
meters/min., maximum. The following high-speed
roller assemblies are optionally available:
“K” Roller Assembly : 3,500 meters/min., maximum
“HS” Assembly : 5,000 meters/min., maximum
All high speed roller assemblies must be initially
installed by the factory or an authorized service
facility.
6.2 Lever Assembly
On high-range instruments, the return spring force
must be strong enough to bring the outer rollers back
to their original position during measurement. The
average person will find it difficult to operate the
mechanism just with thumb pressure on the Thumb
Piece alone. (This is especially true with models rated
20 Kg and higher.) Adding the Lever Assembly shown
here will greatly reduce the effort required to open and
close the 3-roller system. The Lever Assembly must
be installed by the factory or an authorized service
facility.
