Automatic four-point probe pneumatic measurement system

[Feature]

1. Suitable for mass production lines. It is suitable for online measurement of coating quality after sputtering (or other processes) for mass production machines.
2. After accepting the external console trigger signal, fully automatic pneumatic multi-point resistance measurement is performed, and the console is automatically returned after the measurement is completed.
3. Automatically control the three-point (or more) four-point probes to decrease in simultaneity, selectivity, or sequence to complete multi-point resistance measurements. After the measurement is completed, the reward will be automatically increased.
4. Automatically detect the upper and lower positioning sensors, determine the positioning until the next positioning, such as in place will terminate the measurement, and report the error message. In the same way, the determination of the upper position allows the movement of the object under test to ensure safety.
5. Software support engineering model and production model, self-built/access/download recipe. Multiple sets of error messages provide users with troubleshooting.
6. Automatic thermal voltage compensation.
