Mark 10 Corporation / ESM303 Motorized Tension _ Compression Test Stand



The ESM303 is a highly configurable single-column force tester for tension and compression measurement applications up to 300 lbF [1.5 kN], with a rugged design suitable for laboratory and production environments. Sample setup and fine positioning are a breeze with available FollowMe™ force-based positioning - using your hand as your guide, push and pull on the force gauge or load cell to move the crosshead at a variable rate of speed.

With generous travel, clearance, and depth dimensions, a wide range of tests can be performed, including break testing, cycling, limit testing to a load or distance, loadholding, elongation testing, tensile testing, compression testing, and more. Satisfy various test methods through an easy-to-use menu, allowing the configuration of test speed, force and distance limits, cycling, preload, and many other functions, all protected by a password. Save up to 50 profiles to accommodate a range of test methods.

When the ESM303’s clearance is insufficient for the application, its modular mechanical design allows for single- and double-column extensions. Modularity extends to the controller functions as well. Individual functions, such as travel measurement, cycling, loadholding, etc., may be purchased either upfront or enabled in the field through an activation code. This a-la-carte platform allows for custom configuration as appropriate for the application and budget.

Force and travel data can be output to a PC for graphing and analysis using MESUR™gauge software. Or, fully control the stand by a PC through a custom-written program with ASCII communication.

Hardware and Software Options
Safety shield (ESM303-003)
Provides pinch and sample debris protection for the operator. Includes an electrical interlock, preventing test stand operation while the door is open.

Control panel tabletop mounting kit (ESM303-004)
For applications requiring remote use of the control panel. Features an adjustable viewing angle and a base with thru holes for bench mounting.

Data collection & motion control software
Consider MESUR™gauge Plus for force vs. travel or force vs. time data acquisition, plotting, analysis, reporting, as well as motion control. The software coordinates motor start / stop and data acquisition with one click.

Note: MESUR™gauge Plus does not require any optional test stand functions, such as PC Control. If force vs. travel vs. time output is required, order the Travel Indication option. See below section for details.

A wide range of force gauges and gripping fixtures
Interface cable, gauge to test stand (09-1214)
Connects Series 7, 5 and Series 4 force gauges to the crosshead. This single cable is used to transmit data and power. The gauge's AC adapter is not required.

USB cable, test stand to PC (09-1158)
For force and travel data output and PC control.

Load cell / indicator adapter (AC1062)
Accommodates any Mark-10 indicator and Series R01 or R03 force sensors. Includes mounting hardware.

Load cell hardware kit (AC1064)
Set of hardware to adapt load cells with #10-32, 1/4-28, and 1/2-20 mounting threads.

Note that Mark-10 Series R01 and R03 load cell part numbers ending in -1 (ex: MR01-500-1) include all necessary mounting hardware for the ESM303.
Single column extensions (ESM303-001-1 / -2 / -3)
Increase the vertical clearance for tall samples. Multiple extensions may be stacked for very long samples.

Three lengths are available - 6, 12 and 24 in [150, 300, and 600 mm].

Not compatible with the ESM303-003 safety shield.

Double column extensions (ESM303-002-1 / -2 / -3)
Accommodate up to a 20 in. [508 mm] wide sample, or ø21.5 in [ø546 mm] round sample.

Three heights are available - 6, 12 and 24 in [150, 300, and 600 mm]. Base contains rows of T-slots for fixture mounting.

Not compatible with the ESM303-003 safety shield.

Eye end adapters
Allow for quick grip installation and removal, and prevent grip rotation. Mount to common test frames, load cells, and force gauges.




Any of the below functions may be purchased at time of order or may be enabled in the field at a later date though a code activation process. The only exception is the AF009 travel measurement option, which also requires field hardware installation.

A complete options package is also available, including all of the below features at a discounted price.

The test stand is shipped in Demo Mode, during which time all available features are temporarily enabled for 160 hours of operation.

Feature Part No. Description Requirements
FollowMe™ AF008

Crosshead movement responds to manually pushing or pulling on the force gauge shaft or load cell. Increasing force produces greater speeds. Ideal for setups and quick positioning.

Included when ordering the ESM303-003 safety shield.

  • Series 7 or 5 gauge or indicator with load cell
  • 09-1214 interface cable
Travel indication AF009 Travel is indicated on the control unit display, with output via USB. An internal scale utilizing Renishaw technology produces significantly higher accuracy than with conventional rotary encoder-based designs. Backlash and nonlinearity are virtually eliminated.  
  • If data output to a PC is required, add 09-1214 and 09-1158 cables, and a Series 7 or 5 gauge or indicator with load cell.
  • Field activation requires hardware installation. Otherwise, hardware is factory installed at time of order.
Computer control AF010

The ESM303 may be fully controlled by a PC through a custom-written program in any language supporting ASCII communications. Also responds to the legacy Chatillon TCD command set and legacy Nexygen TCD software (not available from Mark-10).

This option is not required for MESUR™gauge Plus software.

  • Series 7 or 5 gauge or indicator with load cell
  • AF009 travel indication
  • 09-1214 interface cable
  • 09-1158 USB output cable
  • For full speed range, consider AF017 and AF018 speed range extensions
Programmable travel limits AF011 The stand stops at or cycles between programmable upper and lower travel distances.  
  • AF009 travel indication option
Overload protection AF012 Protects a force gauge or force sensor against overload. Program the desired percentage of full scale of the gauge. Adjustable analog voltage setting allows the stand to interface with virtually any gauge with analog output.  
  • Series 7 or 5 gauge or indicator with load cell
  • 09-1214 interface cable
Auto return AF013 The crosshead moves to a limit switch, force set point, travel position, or break, then stops and reverses direction at full speed to the opposite limit.  
  • If reversing at force set point: Series 7 or 5 gauge or indicator with load cell, and 09-1214 interface cable
  • If reversing at travel limit: AF011 programmable travel limits option
  • If reversing at break: AF019 break detection option and 09-1214 interface cable
Cycling / dwell time AF014 Same as auto return, but with the ability to program up to 100,000 cycles. Programmable dwell time for upper and lower limits (set independently) can be set up for up to 10,000 seconds.  
  • Same as auto return, at the same speed in each direction. Add AF016 for independent up and down speeds.
Independent Up and Down speeds AF016 Configurable speeds for up and down directions.  


Low speed extension AF017 Extends the standard speed range down to 0.02 in/min (0.5 mm/min).  


High speed extension AF018 Extends the standard speed range up to 45 in/min (1,100 mm/min).  


Break detection AF019 Crosshead stops at a sudden drop in force. Programmable percentage of peak force.  
  • Series 7 or 5 gauge or indicator with load cell
  • 09-1214 interface cable
Loadholding AF020 Dynamically adjusts the crosshead position to maintain a programmed load for an indefinite or specified period of time.

  • If a specified time is required, add AF014 cycling / dwell time option
  • 09-1214 interface cable
Preload / sample touch AF021 Stops the crosshead and/or zeroes the travel display at an initial preload - useful in tensile, compression, spring, elongation, and other applications. Preload is programmable as a percentage of force gauge/load cell full scale. Three modes: (1) stop, (2) stop and zero, and (3) zero without stopping.  
  • AF009 travel indication
  • Series 7 or 5 gauge or indicator with load cell
  • 09-1214 interface cable
