will run for 12+ hours on a charge.

LED changes to green while

charging and does not go out when

Travel Indicator:

Move upper plate down to touch the base & Zero travel – push

the red ZERO 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 compressing 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) sits

on a step in the retainer and is

compressed more than the outer one.

To make the travel read correctly when using

the retainer put the outer step of the retainer

between the upper and lower plates when

Zeroing the travel indicator.

Spring Pressure

Display:

Zero with no load.

Reads in lbs. (or kgm)

Handle can be

length of the springs

being tested.

slide entire pinion shaft

and handle out. Reposition

as needed, reinstall collar

and tighten.
