INTRODUCTION
Thank you for choosing the MTH-550 Force Tester .
The MTH-550 manual tester is designed for basic tension or compression
force testing applications where precision movement is necessary. The
MTH-550 has a force capacity of 550lbf (2500N).
PRINCIPLE OF OPERATION
Rotating the handwheel moves the worm gear assembly 0.03" (0.76mm)
per revolution. The MTH-550 has a full 4" (101mm) stroke.
A DFC or DFC Force Gage mounts to the gage bracket. The gage bracket
may be moved for longer or shorter sample lengths. The force gage
measures the load as the rack assembly moves in either direction.
The handwheel assembly attaches to the column. It may be positioned
anywhere along the column.
An optional digital scale assembly (p/n MTH-SCALE) may be attached
to provide high resolution deflection measurements. The test frame
horizontally on your work surface.
SETUP FOR USE
Locate the MTH-550 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 bracket using four
M4 screws.
Position the force gage on to the gage bracket so that the load cell stem
points downward. Use the force gage display “Flip option” to invert the
display. 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
Affix the test fixture to the force gage’s threaded stem and to the MTH550 worm gear assembly. You may use either threaded test fixtures or fit
the force gage and the test frame with the optional M10 clevis assembly
(p/n SPK-CLEVIS-L). The force gage bracket has been designed to
ensure correct centerline alignment.

PERFORMING A TEST
Apply tension or compressive force on your sample by rotating the
handwheel. As you rotate the handwheel, the worm gear assembly will
move up or down. Rotating the handwheel clockwise will move the gear
upward (compression) while moving counter-clockwise will move the
gear downward (tensile).
HORIZONTAL OPERATION
You may fit the MTH-550 with optional mounting legs (p/n MLX-26030).
This allows you to position the test frame horizontally on your work surface.
