Sep 28, 2026

The following covers the test procedure, test fixture and test results of this experiment. Products of different series and grades can be tested using the same method.

Test procedures:

1. Test the switching response speed at four pressure setpoints: -50.0kPa, -60.0kPa, -70.0kPa and -80.0kPa. Before testing at each setpoint, align the displayed readings of both products to ensure comparability.

2. Connect Oscilloscope Probe 1 to Switch 1 of SP-01C001R, and Oscilloscope Probe 2 to Switch 1 of DP-001.

3. Adjust the test points and repeat the test following steps 1 and 2 above.
