Hydraulic universal testing machine for Photoelectric Instrument Co., a dial Error Analysis

Summary: hydraulic universal testing machine is mainly used for metal, non-metallic, composite materials and products tensile, compression, bending, shear and other mechanical testing of the way, at the same time According to GB, ISO, JIS, ASTM, DIN and provide users with a variety of standard test and data processing.

      Frequently encountered mechanical measurement test instrument, "tension, pressure, and universal testing machine JJG139-1999 Verification Regulation requires its showing the value of allowable error is usually no more than 1%, metrology department metrological verification of degree disc hydraulic universal testing machine , its indication error embodied mainly in the following ways:

      1, showing the value of a positive deviation of tolerance.

      2, showing the value of negative deviation of tolerance.

      Positive after a negative indication error is rendered on
