INTRODUCTION
Thank you for choosing the MTL-110 Force Tester.
The MTL-110 manual tester is designed for basic
tension or compression force testing applications.
The MTL-110 has a force capacity of 110lbf (500N).
PRINCIPLE OF OPERATION
Rotating the lever arm moves the rack and pinion
assembly 3" (76mm) per revolution. The MTL-110
has a full 6" (152mm) stroke.
A DFC or DFG Force Gage mounts to the gage mounting
plate on the rack assembly. The force gage measures
the load as the rack assembly moves in either direction.
The top test fixture arm is used to affix the test
fixture. This arm has an adjustable plate to help
ensure proper axial loading on the sample and on the
force gage’s load cell sensor.
A locking hub is used to prevent backlash during testing.
The MTL-110 may be fitted with the optional digital
scale assembly (p/n MTL-SCALE) for high resolution
deflection measurements.
SETUP FOR USE
Locate the MTL-110 tester where there is sufficient
clearance for testing and moving the lever arm.
You may permanently secure the base to the work
bench using flat head screws. Use the four corner
hole locations to secure to your work bench if
desired. Remove the hole plugs to reveal the 0.25"
clearance holes.

MOUNTING FORCE GAGE
The DFC or DFG Force Gage is mounted to the gage
mounting plate using four M4 screws.
Position the force gage on to the gage mounting plate
so that the load cell stem points upward. Insert and
torque the four M4 mounting screws through the gage
mounting plate and into the force gage back panel.
Torque the screws to no more than 8.7 in-lb (1.0 N-m).
USING FIXTURES
The top test fixture arm is used to secure the top
test fixture. The test fixture arm has an adjustable
adapter plate that helps ensure proper alignment
with your force gage. The adapter plate has an M6
and a #10-32 hole for affixing your test fixture.
Rotate the adapter plate 180-degress to access the
desired hole size.
The two outside holes are used to secure the adapter
plate to the U-channel bracket.

PERFORMING A TEST
Apply tension or compressive force on your sample
by rotating the lever arm. As you rotate the lever,
the entire rack and pinion assembly will move up
or down. Rotating the arm clockwise will move the
rack assembly 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.
USING THE OPTIONAL DIGITAL SCALE
The MTL-110 may be fitted with the optional digital
scale (p/n MTL-SCALE). 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.

USING THE OPTIONAL LEGS FOR
HORIZONTAL OPERATION
You may fit the MTL-110 with optional mounting legs
(p/n MLX-26030). This allows you to position the test
frame horizontally on your work surface.
HORIZONTAL MOUNTING KIT (P/N MLX-26030)
Includes two (2ea) mounting legs, an end cap (not
shown) and all necessary mounting hardware.
Replaces the standard baseplate for horizontal testing.
