Peak Hold
APPLICATION: Up to 10 broken points of the material are detected at compression and tension testing
machines. All peak values of testing can be shown on the display automatically after the testing or by pressing
programmed key to the LAST test.
RELATED PARAMETERS: Sub-blocks 31- and 32-. Parameters 241, 242 or 243.
The tension testing process is shown in the diagram below.

END DECR:
Force decrease to finish the test.
STOP:
Stop testing if the force is bigger,
