The spring tester is an instrument that specifically tests the spring. As an instrument for testing the performance of springs, Jinan Jin Sanfeng Instruments & Equipment Co., Ltd. has many roles in the spring testing machine. Specifically, the spring testing machine can re-analyze the curve of the spring test, and can zoom in, zoom out and click to see the curves. The data corresponding to the points is suitable for batch testing and sorting of springs on the production line, and also suitable for precision sampling of laboratories.
Spring testing machine troubleshooting methods are as follows:
1, switch no display Check 220V power supply and microcomputer system power supply is normal? If the fuse is disconnected, it should be replaced;
2. If the power plug is in poor contact, it should also be replaced;
3. If there is no output from the power transformer, replace the transformer or rewind the transformer;
4, if the voltage regulator circuit is not normal, then check the corresponding bridge diodes and filter capacitors and the corresponding connection lines, replace the damage, welding or open circuit should be re-welded.
5, check the digital circuit voltage is +5V? If not, there will be a cold or open circuit between the regulated power supply and the digital connection.
6. Check whether there is any short circuit point in the 5V load circuit? If yes, remove it, clean and dry, or replace components.
7, check the digital tube voltage is normal? Check the sensor is normal? If the above conditions are normal, the op amp is damaged and should be replaced. If the value of 220V is not stable, a regulated power supply must be configured. If the amplifier output voltage is not stable, replace the amplifier.
8, check the CPU frequency (11.0592MHz) and compare the voltage is stable or drift? If there is a problem of imaginary welding, re-welding should be performed; if the performance of components deteriorates, it should be replaced to check whether the circuit board is damp or oily, and perform necessary cleaning and dry processing.
The above is a brief introduction to the troubleshooting of spring testing machines. For more information about spring testing machines, call our staff directly.
