main features ：

1. Hanging code method: automatic loading, controlled by a DC motor, with low noise and minimal shaking. Easily control hanging and unloading codes through the mini keyboard.

2. Framework: Composed of aluminum profiles, with good levelness, easy installation, and easy extension of length in the future, the design is beautiful and practical.

3. Clamping mechanism: The clamping device can fine tune the X-axis, quickly and accurately zero. The clamping surface adopts joint ball head adjustment to improve the contact of the clamping magnetic surface and avoid sideslip caused by the tape hanging code.

4. The measurement system can batch input the calibration information of the inspected ruler, automatically read the steel tape scale by selecting lines, calculate errors, display and store the measurement data, and automatically generate original records, calibration certificates, etc.

Technical indicators

5. Range: The calibration table has a length of 5m and can be customized from 5m-50m according to user needs. The segmented method is used to measure (1-100) m steel tape measures；

6. The steel tape measuring platform is equipped with 6 high-definition industrial cameras, which can measure the position according to the needs and be adjusted conveniently。

7. Standard steel tape measure：±(0.03mm+3*10^-5L)。

8. Reading microscope resolution：0.01mm ；

9. Verification table support axis table straightness：≤0.5mm/m；

10. The magnification of the reading microscope is 20X;

11. Effective field of view of reading microscope: 6mm;

12. Friction force: The friction force between the calibration table and the tested ruler is ≤ 4N;

13. The measurement system can input the calibration information of the inspected ruler in batches, and select the line pattern in the box

Automatically read the scale error of the steel tape measure, display and store the measurement data, and make judgments on whether the measured steel tape measure meets Class I, Class II, and unqualified according to the JJG4-2015 Steel Tape Verification Regulations. Automatically generate data records for reference and printing. At the same time, it can also calibrate measuring instruments such as fiber measuring tapes and measuring ropes;
