KALPAK Spring Testing Software is Windows based, user-friendly software designed for the test data acquisition & logging in file format on PC. The test data is acquired through serial PC port and logged to provide tabular display. It fulfils the basic functions like load and length measurement as well as calculation of free height, deflection and preset load and load at present length or spring rate.
User-friendly screen with complete evaluation and presentation of test results in tabular and graphical formats.
Easy to load, Easy to operate, no special training required.
Online mode to receive mode options.
Report Screen is used to make data entry and o generate reports, Layout design of parameters, results can be pre-programmed as per user requirements.
Easy access to results of past test data.
