What is the zoom on the video camera …or what are the smallest sized grains that can be seen in the video camera?
The standard zoom lens allows 20X to 200X. However, adding an optional 2X lens will double this range (i.e., 40X to 400X). You will be able to see the grains on the polished and etched sample. top 13. What is the slowest data acquisition rate (for long-term creep tests)? Also, is the listed 500 samples/s data acquisition rate correspond to all the channels (i.e. load, displacement, temperature, time) or only a single channel? The slowest data acquisition rate is either one sample per second or one per minute or per hour. We have developed a unique indentation creep software which allows to select various data acquisition rates for different time periods of the creep test (specially for the first few minutes of the test). It is also important to note that materials might have different creep properties under multi-axial deformation than under a single axis deformation. We proved that some carbon steel samples creep at room temperature under the multi-axial deformation of the ball indent
