The principle of work of the present utility model and the course of work:
The preparation of test: instrument energising preheated one-section is after the time, earlier by " zero clearing " key, make instrument enter normal operating conditions after, during the system of entering is provided with, check that whether option is set changes, as change to some extent, then change, withdraw from as not changing then according to the method for revising.Remove zero point by " zero clearing " key.
Load test; Before beginning to load, the sample of packing into begins to load, and after instrument internal detects the power value, begins to show the power value, and after the test specimen pressure break, instrument writes down the peak value of this time test automatically.Test by another test specimen that " test " key can carry out in this group sample, the whole specimen tests in this group sample are intact, can carry out the operation of the 3rd step then.
Print data: after the whole specimen tests in this group sample finish,, begin to print the sample data of this group sample by " printing " key.As not printing, only need not according to " printing " key.
After battery of tests finished, instrument entered next group number automatically, can begin the test of next group sample, repeated two, three, four operation.
Instrument can realize that process of the test controls automatically.Automatically lock brokenly the type peak value, can print test findings.Can preserve test figure automatically, power down also can be preserved, and can preserve 500 groups of data (one group of data can be monolithic data or 3 data) altogether.And can inquire about and print the data of preserving.Test figure is reliable, and is easy to operate.
When instrument is in the measurement state; press once " test " key; promptly can finish successively " rising " → " etc. speed loading " → " broken type " → " peak value maintenance " → " decline " (will be immediately by " stopping " key when dropping to anchor clamps and leave pressure head; otherwise will reduce to lower limit automatically); and the auto stop overall process, use very convenient.
