Main differences when using a spherical vs cylindrical indenters
Here are the main differences when using a spherical vs cylindrical indenter: Spherical Shaped Indenter Cylindrical Shaped Indenter A model should be used to fit to this data (Hayes, Hertz, Sneddon). See Mach-1 Analysis User Manual for more ...Multi-axis Load Cell FAQ
Note that for version 4.5.0.1 of Mach-1 Motion or later with an ESP302 controller + interconnection board + load cell smart connectors, the load cell calibration matrix is hardcoded and must be modified by a Biomomentum technician. How are multi-axis ...No data stream when opening Mach-1 Motion, then Error -88705 after a few minutes
The general Error -88705 can be solved using the following method: https://support.biomomentum.com/portal/en/kb/articles/daqmx-self-test-error-88705 In this specific case of the error, there is a blank screen (no load cell data is shown) for a few ...Questions and Answers regarding Spherical Indentation of Cartilage
Is there a suggested Poisson's ratio to use when analyzing indentations? If an indentation is performed in 1 second or less, it can normally be considered "instantaneous" and a Poisson's ratio of 0.5 should be used (i.e. the liquid inside the sample ...Questions and Answers regarding the Hayes model (1972)
What is the Hayes model (1972)? The Hayes model is a mathematical model developed for indentation tests of articular cartilage. The articular cartilage is modeled as an infinite elastic layer of a certain thickness bonded to a rigid half space. This ...

In the case where the stage does not move when "Up" or "Down" are clicked, it is likely that the stage has been turned OFF. To turn the stage back ON, click "Enable Axis" or "Enable Axes" in the "Manual Controls" window. Stages will automatically ...Verify the actuator controller connection and/or power (Error code: -1073807339)
Error code: -1073807339 can appear for multiple reason. The most common reason is that the ESP controller power button is off. To fix this error, reach behind the Motion Controller and activate the switch powering ON the ESP controller. Other ...Camera related errors (Error: 5003, Error: -200279)
The camera integration into Mach-1 Motion is very intensive on the PC. If Mach-1 Motion is not able to run smoothly and starts losing data, an error will appear. To minimize the likelihood of camera errors, try the following suggestions: ALWAYS save ...
