USING THE OPTIONAL DIGITAL SCALE
The MTL-330 may be fitted with the optional digital
scale (p/n MTL-SCALE330). The scale will display
distance measurement for your test. For example,
you can use the digital scale to measure and display
spring deflection to determine the spring rate for a
compression spring. The scale will measure either
tension or compression distances.
PERFORMING A TEST
Apply tension or compressive force on your sample by
rotating the lever arm. As you rotate the lever, the rack
and pinion assembly will move up or down. Rotating the
arm clockwise will move the rack and pinion upward
(compression) while moving counter-clockwise will
move the rack assembly downward (tensile).
The locking hub should be tightened slightly to provide
some friction to the movement so that the lever cannot
reverse rotation (backlash) when under load.
CAUTION
The lever arm can reverse direction unless secured by the
locking hub. Use the locking hub to prevent backlash.
