The arithmetic mean of the measurement point measurement technology: F is the key point of the measurement, quality test F: the maximum value F... measured at the same continent or point Get the value of the small value in the test - less transmission feeling, the test machine force indicator can be installed! Force reading value, for the lack of low-level force reading - group test disk, test force increase. Test the machine force indicator on the way to verify the value of the indication on the test force indicator, even the standard cloth measuring instrument reading, your value is different, you use the heavy h.

In the formula, ---… the arithmetic mean value of the same measuring point; Fm-the segment fire value of F measured at the same measuring point; F
-the minimum value of F measured at a single measuring point: when the test force decreases, the actual force indicated by the standard dynamometer! 5)
Comparison, for the entire process of the low-level force used, for a group of measurements, when the test force increases, the standard The measured force is only the actual force indicated.
The same relative deviation control formula is calculated as:

Where: The test force indicator is set before the test force F, and the test force is set before the test force is set. The test force value at the point of 20% of the maximum test force of each level is calculated as follows:
Where: The resolution F of the test force indicator is the test force value at the point of 20% of the maximum test force of each level. Responsibility: For the lower scale dial indication installation width, the half-day pointer is also the ratio of the two cabinets to the loading report (1/2-1/61/13) English accurate, and the estimated reading percentage value is 2.5 smaller than the original. For the dry type cabinet indication, the secret teaching digital road indication value is a small increase in the single meter of the sample car force,
