Note: For full operation out of the box, you will need control functions (sometimes optional depending on the application), a Force Gauge, Grips/Attachments to secure the sample, software, and cables (including but not limited to, the 09-1214 interface cable or the 09-1158 USB cable, which are options available above on this product page).

ESM303 from Mark-10 is a high configurable single-column motorized force tester for tension and compression measurement applications up to 300 lbF, with a rugged design suitable for laboratory and production environments. ESM303 makes sample setup and fine positioning a breeze with the available FollowMe force-based positioning function. This new function allows the operator to use their hands to 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 tension and compression tests can be performed including break testing, cycling, limit testing to a load or distance, load holding, 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 load holding, 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.

ESM303 Features

  • Selectable speed setting
  • Adjustable, removal controller with intuitive menu navigation
  • Upper and lower travel limit switches
  • Stepper motor driven, producing smooth and quiet operation with no speed variation under load
  • Password protection of test parameters
  • Ergonomic design, with smart, clean cable management
  • Compact footprint suitable for crowded workbenches
  • USB output of force vs. time or force vs. travel
  • Integrated electronics assembly easily removed and transported
  • Adjustable mounting plate with T-slot base

Optional Functions

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

A complete options package is also available, including all of the below functions at a discounted price. The test stand is shipped in Demo Mode, during which time all available functions are temporarily enabled for 160 hours of operation.

Functions Part No. Description Requirements
FollowMe™ AF008 Crosshead movement responds to manually pushing or pulling on the load cell. Increasing force produces greater speeds. Ideal for setups and quick positioning.
  • Model M7i or M5i indicator
  • 09-1252 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 09-1252 and 09-1158 cables, and a Model M7i or M5i indicator.
  • Field activation requires hardware installation. Otherwise, hardware is factory installed at time of order
Computer Control AF010 The ESM303H may be fully controlled by a PC through a program written 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.
  • Model M7i or M5i indicator
  • AF009 travel indication option
  • AF011 programmable travel limits option
  • 09-1252 interface cable
  • 09-1158 USB output cable
Programmable travel limits AF011 The stand stops at or cycles between programmable right and left travel distances.
  • SF009 travel indication option
Overload protection AF012 Protects a load cell against overload. Program the desired percentage of full scale of the load cell. Adjustable analog voltage setting allows the stand to interface with virtually any instrument with analog output.
  • Model M7i or M5i indicator with load cell
  • 09-1252 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: Model M7i or M5i indicator with load cell, and 09-1252 interface cable
  • If reversing at travel limit: AF011 programmable travel limits option
  • If reversing at break: AF019 break detection option and 09-1252 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 right and left 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 right and left speeds.
Independent right and left speeds AF016 Configurable speeds for right and left 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.
  • Model M7i or M5i indicator
  • 09-1252 interface cable
Loadholding AF020 Dynamically adjusts the crosshead position to maintain a programmed load for an indefinite or specified period of time.
  • Model M7i or M5i indicator
  • If a specified time is required, add AF014 cycling/dwell time option
  • 09-1252 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 option
  • Model M7i or M5i indicator
  • 09-1252 interface cable
Profiles AF022 Save and recall sets of test parameters, such as speeds, travel limits, preloads, etc. Up to 50 profiles may be stored.
Complete options package AFCOMP Includes all functions listed above, plus 09-1252 interface cable and 09-1158 USB cable.
Requires a Model M7i or M5i indicator.
