Abstract
PURPOSE: To enable the recording of the results in the long time test on a recording paper with a limited length by controlling the feeding of the recording paper in a recorder with logarithmic conversion of the time elapse in the test of material or the like.
CONSTITUTION: A logarithmic conversion is made on the time progress of tests by way of a counter 4 adapted to count the frequence of repeating load application in a fatigue test or the like of a sample 1 such as reinforced plastic material which is conducted with a tester 3 and a logarithm converting means or the like such as logarithm amplifier. The feeding of a recording paper 7 in a recorder 6 which is designed to record with a recording pen 14 adapted to be displaced according to stress or the like measured through a distortion meter 11 is controlled according to the time axis converted logarithmically. Accordingly, it is possible to record the results of long-time tests on a recording paper with a limited length without the use of the one with a length otherwise necessary when it is fed to match the time axis changing in linearity.
