I. Overview

This testing machine is a special instrument for testing the relationship between the deformation and load of the tension and compression spring.Working load test under certain working length of tensile and compression spring is adopted.The testing machine adopts advanced and high integration integration Microcontroller, and the Chinese liquid crystal display, the appearance of a metal shell, greatly improving the system's anti-jamming capability.

II: Features

1, Chinese liquid crystal display, better human interface

2, high-precision high-resolution

3, three kinds of measurement units can be selected, mutual conversion

4, the user can set their own use of gravity acceleration, the test and unit conversion more accurate

5, 99 sets of test data storage, can be stored directly on the machine to view and delete data.

6, real-time, peak, automatic peak three modes are free to switch

7, with customer settings, free to set the upper and lower limits (corresponding to the sound and light alarm), stored value, hold value, automatic peak storage time, no automatic shutdown time, free to set

8, print the stored test data and the maximum, minimum, average, do qualified or failed to judge (only with a printer)

9, communication MODBUS-RTU standard protocol, using the USB interface to better configuration and PLC connection

Third, the key instructions

1, set the key: the user in the measurement interface through this key to enter the setup menu, and set the data, press this key to save the data.

2, check the key: in the measurement interface through this key to view the stored measurement data

3, the peak key: used to switch real-time, peak, automatic peak three measurement modes

4, save key: used to save the measured data

5, the unit key: used to switch N, Kg, Ib three units

6, Zero key: Press this key to adjust the zero point in the real time measurement, press this key to clear the peak value and return to zero point in peak value and auto peak value; Press to save the measured value, press this button to clear all stored measurement value, press this key to return to the previous interface without saving the data.

7, Print button: In the measurement interface, press this button, you can print the stored measurement value (no print function of the machine except)

8, Up key: In the user setting interface, press this key to modify the setting item. When the parameter is set, press this key to select the digit to be changed. View the previous data.

9, Down key: In the user setting interface, press this key to modify the setting item. When the parameter is set, press this key to modify the data in the current position. data.

10, ON / OFF key: can be used to boot, and shutdown
