If independent up and down speeds are enabled, UP SPEED and DN SPEED parameters will be present, and may be set individually. Default setting: 10 in/min Available settings: 0.02 – 45 in/min UP SPEED : ESC Label − 10 .
Model ESM301 / ESM301L Version 2 Test Stand User’s Guide 4.3 Cycling (CYCLES) This setting allows the user to configure the number of up and down cycles through which the crosshead will sequence. One cycle consists of the crosshead moving to a limit switch or soft limit, whichever occurs first, at the specified speed, stopping for the specified amount of dwell time, and returning to the other limit at the specified speed.
Model ESM301 / ESM301L Version 2 Test Stand User’s Guide 4.5 Upper and Lower Travel Limits (UPPER LM and LOWER LM) This setting corresponds to the travel distance the crosshead moves before stopping or cycling. Upper and lower limits are programmed individually. The programmed distances are relative to the zero position of the crosshead. The travel indicator can be zeroed by pressing and holding STOP for 3 seconds. Default settings: +12.000 in, -12.000 in Available settings: From -19.000 to +19.
Model ESM301 / ESM301L Version 2 Test Stand User’s Guide 4.7.1 Preload (PRELOAD) This setting corresponds to the test stand’s response to an initial load, referred to as a preload. The crosshead can stop and/or zero the travel display when the preload has been reached. This function is useful for applications such as spring testing, elongation testing, and tensile and compression testing of various materials. For details about setting the preload value, refer to Section 4.7.2.

Crosshead movement will take place until a limit has been reached. If the crosshead has stopped at a soft limit, the limit condition may be overridden by pressing and holding UP or DOWN. 5.3.1 Travel Indication If enabled, travel indication is displayed in the upper left corner of the display.
Model ESM301 / ESM301L Version 2 Test Stand User’s Guide 3. Crosshead reverses direction, returns to the other limit at the specified speed, and stops for the specified amount of dwell time. A cycling sequence can be initiated from any position and can start in either direction. If the crosshead is at a limit, however, cycling can only be started in the direction of the other limit. To initiate a cycle sequence, press UP or DOWN.

Note 2: Preload and Load Holding cannot be enabled simultaneously. 5.6 Load Holding Mode In this mode, the crosshead moves until the set point value programmed in the force gauge is reached. The crosshead then dynamically adjusts its position to maintain a programmed force. The force gauge’s capacity should be as close as possible to the intended load, for best performance. In the force gauge, both set points must be set.

Model ESM301 / ESM301L Version 2 Test Stand User’s Guide 6 COMMUNICATING WITH MESURTMGAUGE The ESM301 can communicate with MESURTMgauge data collection software. The test stand can output either force data only or force data combined with travel data (if the ESM301(L)-001 integrated travel indication option is installed). To communicate with MESURTMgauge, certain settings in the test stand and force gauge are required, as follows: 1. Check physical connections (refer to Section 3.4) 2.
Model ESM301 / ESM301L Version 2 Test Stand User’s Guide An example is shown below: KEYS : E SC 0139027 + − ENTR The request code must be supplied to Mark-10 or a distributor, who will then provide a corresponding authorization code to activate the feature. The process for entering the authorization code is as follows: 1. The first digit of the request code will be flashing. Press + to increment the digit. Pressing + when the number 9 is displayed will return to 0. 2.
Model ESM301 / ESM301L Version 2 Test Stand User’s Guide To clear any of the above errors, press STOP. The amber light in the STOP button will be blinking when the error message is displayed. 2. The crosshead will move only in one direction, or not at all. Possible causes: 1. Ensure all cables are plugged in properly, as described in Section 2.2. 2. Ensure that the force value has not exceeded the overload limits configured in the gauge. 3. Ensure that force gauge set points have been configured properly.
Model ESM301 / ESM301L Version 2 Test Stand User’s Guide subcomponents of the test stand (ex. fasteners, brackets, etc). All components should be firmly attached. If any looseness is detected, stop using the test stand and contact Mark-10 or a distributor for instructions. 10 SPECIFICATIONS Load capacity: 300 lbF [1.5 kN] @ up to 24 in/min [610 mm/min] 200 lbF [1 kN] @ >24 in/min [>610 mm/min] 0.5-13 in/min [13-330 mm/min] ESM301: 11.5 in [292 mm] ESM301L: 18.0 in [457 mm] ±0.
