Function Description:
1. Power specification: 110VAC/60Hz/1Φ/1A.
2. This test system is a customized product, designed and produced in accordance with the requirements of the key
switch 2a/2b action sequence diagram provided by the customer, as follows The function is areference sample.
3. This test system measures one each when the 2c (2a/2b) key switch is pressed, when the contact is pressed
(OFF→ON) and when the contact is released (ON→OFF) Time, the time test pattern of the action sequence is
displayed on the screen, and the interval time of its switching action will be automatically displayed at the same
time. The maximum interval of the displayed time can be self-defined interval time.
4. The fastest signal sampling time is 10 us/S, the sampling length is 20ms (2000 points), the screen display scale can
set the time axis to zoom in The X-axis waveform interval. Five. Each group of key switches has two groups of 1c
(1a/1b) contacts, and 4 signals (1a.1b, 2a. 2b) are read each time they act, and the timing difference is calculated on
1b. 2a. 1 group; when 2b.1a is another group of actions, compare the timing difference of the contact action of each
group, and use the action provided by the purchaser of this test system Display the time sequence graph as an
analog waveform, and you can observe the bounce waveform diagram of each contact action and the comparison
information of the time sequence difference.
6. The test working voltage is 14VDC (0.5A*2=1.0A).
7. Data capture every time a single set of key switches is actuated for testing in Real-Time mode.
8. The screen shows the action sequence diagram according to customer needs, and marks the 10V and 4V detection
voltage level line and the vertical line at the intersection of the timing difference. The time difference of the
intersection point of the sequence difference in time.
9. The hardware equipment of this test system is a single set of loops. The test screen can display up to four channels,
and the four channels share a single set of loops. Detect a channel (manual selection is required), and for each channel,
you can observe two groups of button action bounce waveforms, which are the button switches (OFF→ON) and key
switch (ON→OFF).
10. The test system adopts PC-BASE and Real Time design, which shows the test of the timing difference of the single set
of key switch 2C (2a/2b) contact action. Waveform graph and test value, and can set the upper/lower limit range of
the time sequence difference to control the function to record the OK/NG judgment result, record And count the yield
rate, real-time utilization rate, including (maximum, minimum, average, standard deviation, (Cp, Ca, Cpk) value and
other SPC Statistical analysis data, etc., data are recorded in Access database.
