Cooper Instruments ESMH Installation Manual
ESMH TEST STAND USER GUIDE
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 Cooper Instruments at 800344-3921.
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.

MOUNTING FORCE GAUGES
To mount a force gauge, it is necessary to temporarily remove the gauge
adapter from the crosshead. Loosen the tow 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 beside the motor. See illustration below.
