1. High precision and high resolution: accuracy 1, minimum reading 0.001N; 2. Three display options: real-time, peak, and automatic peak; 3. Three conversion units: N, kg, lb 4. Peak hold function: capture the test peak; 5. Comparison function: the upper and lower limits are set freely, and the alarm lights automatically alarm for traffic lights and peaks; 6. Automatic peak value function: the peak value holding time (1～99 seconds) can be set freely; 7. Automatic shutdown function: 0~99 minutes without operation automatic shutdown (0 seconds without automatic shutdown); 8. Gravity acceleration function: According to different regions, it can be set freely (9.000～9.999); 9. Calculation function: connected to a computer, it can automatically calculate the maximum value, minimum value and average value of each test; 10. Built-in printer: can print 99 groups of stored measurement data and maximum, minimum, average, etc.
