Pressure value K1 and K2 is unequal, and travel values L1 be equal to L2 when, the compression bar switch (131) position be push type sensor
Pressing zero-bit；
S3：Product presses measurement process：After zero-bit confirms, slide unit driving testing pressure head (6) continues movement and compresses compression bar switch
(131) terminate to the pressing stroke of push type sensor, after the numerical non-linear variation of pressure sensor (5), determine pressing
Process terminates, and during pressing, the pressing force of test compression bar (6) and movement travel are in pressure sensor (5) and stroke sensing
Device feeds back to industrial computer system under the action of (12)；
S4：Product pressing measurement process terminates, and slide unit driving testing pressure head is retracted, and stroke touches plate (4) and stroke compression bar (9) point
From testing pressure head (6) is detached with compression bar switch (131), and a test period terminates.
