Travel Indicator:
Move upper plate down to
touch the base & Zero
travel - push the green
ON/O button. Or you can
Zero anywhere along the
travel.
If you Zero when the upper plate
just touches the spring it will
read the amount you are com-
pressing the spring. Or you can
set the stop on the rack at the
top to duplicate readings.
If you are checking inner
and outer springs you
should check them with
the retainer as the inner
spring(s) sit on a step in
the retainer and is com-
pressed more than the
outer one.
To make the travel read correctly
when using the retainer put the
outer step of the retainer be-
tween the upper and lower
plates when Zeroing.
