INTRODUCTION
The ESMH motorized test stand is a horizontal force measurement
tester designed to test up to 50 lb [250 N] of tensile or compressive
force. The ESMH works in conjunction with a force gauge and gripping
fixtures. Common applications include peel testing, small spring testing, coefficient of friction testing, and other product performance testing.

SAFETY TIPS
■
Wear eye and face protection when testing. Although the ESMH
has relatively slow moving mechanisms, be aware of the dangers
posed by potential energy that can accumulate in a sample during
testing.
■
Keep away from the moving parts of the test stand.
■
Never operate the test stand if there is any visible damage to the
power cord or the control unit. The ESMH is powered by 110/220V
AC current that is present in both the power cord and the control
unit. Any contact with this high voltage can cause serious injury or
even death.
■
Ensure that the control unit is kept away from water or any other
liquids at all times.
■
Make sure the electrical outlet powering the test stand has local
earth ground (3-hole outlet).
■
Opening up the cover of the control unit is not recommended, as
there are no user-serviceable parts inside. If you wish to open it, be
sure to disconnect power before doing so. If any repairs are
needed, contact Mark-10 or your distributor.
SETUP
Mounting to a workbench
Place the ESMH on a clean, flat and level work area that meets the
criteria outlined in the work area safety instructions. For accurate readings, the area should be free of vibrations.
If desired, the test stand can be mounted to the work area with four
5/16 screws.

About the digital travel display (optional)
The travel display covers 12” of travel with a 5digit display (0.0005” resolution) and a computer
interface for automated data collection. Use cable P/N 09-1066 to output data to a PC.
Complete instructions are provided in a separate
user’s guide (included with the digital travel display).

Mounting force gauges
To mount a force gauge, it is necessary
to temporarily remove the gauge
adapter from the crosshead. Loosen the
two 5/16 screws (shown at left) using
the included tool kit. Then, mount the
gauge to the adapter using the four included gauge mounting screws. After
the gauge is mounted to the adapter,
mount the adapter back onto the crosshead with the 5/16 screws.
Mounting grips and fixtures
The ESMH includes a loading plate to
which a grip or fixture may be mounted.
This plate can be mounted to the end of
the stand with four screws (shown at
left). Before mounting the loading plate,
mount the grip or fixture to it, using the
matrix of tapped holes if required.
Setting up the controller
Plug the controller cable into the 9-pin male connector located beside
the motor. See illustration below.

1. SPEED CONTROL DIAL
Adjust speed by turning the dial 0.2 – 50.0 in/min [5 – 1270 mm/min].
2. LEFT
Press and hold to move the crosshead to the left, producing compressive force.
Release button to stop motion.
3. RIGHT
Press and hold to move the crosshead to the right, producing tensile force. Release
button to stop motion.
4. CONTROLLER CABLE
Plug this cable into the lower connector on the test stand, adjacent to the motor.
5. POWER SWITCH
Use this switch to turn on and turn off power to the load frame. Power is indicated
by illuminated indicators on the face of the controller and load frame.

Powering up
Plug the power cord into the controller and the other end into a wall
outlet. Then turn on power with the power switch (see Page 5).
Reading the indicators
POWER
Power is indicated by an
illuminated indicator.

in compression.
RIGHT LIMIT
Indicates a limit condition in
tension.
Using the limit switches
Limit switches are included to
allow the operator to set travel
limits during testing. This feature
is particularly useful for spring
testing, elongation testing, and
other applications where stopping
at a predetermined position is a
requirement.
The limit switches are located in
the rear of the load frame. Their positions can be adjusted by loosening
the thumbscrews (shown at left), sliding them to either side, and retightening. During testing, when a travel limit has been reached, an
indicator will be illuminated (see illustration above) and the crosshead
movement will stop.
Note: To maintain smooth functioning of the stand, avoid overloads.
