1 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.
2 UNPACKING

4 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 seri-
ous 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.
5 SETUP
Mounting to a workbench
Place the ESMH on a clean, flat and level work area that meets the criteria out-
lined 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.

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 to left.

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. Re-
lease 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 indi-
cated by illuminated indicators on the face of the controller and load frame.

LEFT LIMIT
Indicates a limit condition
in compression.
RIGHT LIMIT
Indicates a limit condition in
tension.
POWER
Power is indicated by an
illuminated indicator.
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
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 appli-
cations where stopping at a predetermined
position is a requirement.
The limit switches are located in the rear
of the test stand. 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 indi-
cator will be illuminated (see illustration above) and the crosshead movement
will stop.
About the digital travel display (optional)
The travel display covers 12” of travel with a 5-digit 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).
