ASM3.0 LCD, automatic residual stress detector

Applicable to a variety of linear-elastic residual stress measurement in solid materials can also be used for strain measurement, stress testing features:
1, automatically switching, time-static strain measurement of 3-way
2, elastic modulus can be set to measure a variety of materials, static stress
3, automatically detects the calculation of residual stress (σ1, σ2, θ).
4, blind hole to release coefficient can be calculated automatically.  It not only applies to blind hole strain release factor A, B are known materials, for blind-hole strain release factor of the unknown material can also be related to the theoretical formula for a more accurate conversion factor, measure the residual stress.  In fact, a large number of tested materials, A, B is unknown, it is not feasible or not with the experimental calibration.  It would not be very different materials with different A, B, residual stress calculation results will be totally wrong. Strain release due to different coefficients of the material may vary very large, the automatic detector for residual stress in A, B unknown materials, the residual stress measurement is very convenient and accurate.
5、三路应变共用一个补偿片
 6, with a USB interface that can transfer data to the outside world, or into the PC re-treatment.
7, fast, large memory capacity
9, single-color 5.7-inch LCD
10, embedded printers, online printing results, such as: principal stress σ1, σ2 and the principal stress direction θ, and displayed on the LCD. 
11, strain measuring range: 0 ~ ± 65000με
12, strain resolution: 0.1με 
13, strain gauge sensitivity can be set to
14, Poisson's ratio, the release coefficient can be set to
15, Zero drift: ≤ 1ppm / h
16, Zero Drift: (1ppm × load value of +0.004 μV) / ℃ 
17, full-scale temperature performance: 1ppm / ℃ typ
18, full-scale temporal stability: ≤ 1ppm
19, strain detection linear: ≤ 0.01%
20, the resistance balance range: ≤ 10% 
21, not only can overcome the strain gauge at the impact of temperature, but also to overcome the strain gauge at the impact of temperature, it could apply to a larger temperature difference between the temperature is extremely harsh environment.
22, which itself can store a large number of mass measurements, and easily list, query, print.
23, the device uses monochrome LCD screen and dedicated user-friendly chassis, and intuitive to use and convenient. 
24, using the drop-down menu interface, a variety of options and a variety of workpiece materials parameters of the input or query is very convenient.
