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).

User’s Guide
■ 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 5/16-18 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. 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.
6. POWER PLUG RECEPTACLE
Plug the power cord in here.
7. FUSE
1.2 A, 250V, 3AG SLO BLO
Note: To maintain smooth functioning of the stand, avoid overloads.

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.
RIGHT LIMIT
Indicates a limit condition in
tension.
LEFT LIMIT
Indicates a limit condition
in compression.
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 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
indicator 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).
