| Optional Controller Functions

Feature Description Requirements



Crosshead movement responds to manually pushing or pulling on the force gauge shaft. Ideal for setups and quick positioning.

M7 or M5 gauge

09-1214 interface cable


Travel Indication

Travel is indicated on the control unit display, with output via USB. 

M7 or M5 gauge

09-1214 interface cable




The ESM303 may be fully controlled by a PC through a custom-written program in any language supporting ASCII communications. This option is not required for Mesurgauge Plus software.

M7 or M5 gauge

09-1214 interface cable and 09-1158 USB output cable


Programmable Travel Limits

The stand stops at or cycles between programmable upper and lower travel distances. AF009 travel indication


Overload Protection

Protects a force gauge or force sensor against overload.

M7 or M5 gauge

09-1214 interface cable


Auto Return

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: M7 or M5 gauge 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

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

Configurable speeds for up and down directions. -


Low speed extension

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


High speed extension

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


Break detection

Crosshead stops at a sudden drop in force. Programmable percentage of peak force.

M7 or M5 gauge

09-1214 interface cable



Dynamically adjusts the crosshead position to maintain a programmed load for an indefinite or specified period of time.

M7 or M5 gauge

If specified time add AF014

09-1214 interface cable


Preload/sample touch

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.

M7 or M5 gauge

AF009 travel indication

09-1214 interface cable



Save and recall sets of test parameters, such as speeds, travel limits, preloads, etc. Up to 50 profiles may be stored. -


Complete options package

Includes all functions listed above, plus 09-1214 interface cable and 09-1158 USB cable. M7 or M5 gauge
