4. Operation
The TMR-02M module can be started either manually by pushing START (#9, Figure 5)or by
a TTL HI signal (rising edge) at TRIGGER IN (TTL) (#7, Figure 5). This signal must be at
least 10 µs.
The time course of the signals at input and outputs is illustrated in Figure 6.
Figure 6: scheme of operation
At the beginning of the DELAY time a TTL signal (+5 V, 1 µs) is generated at TRIGGER
OUT. This TTL signal can be used to trigger an oscilloscope. After the DELAY, the PULSE
starts immediately. After the end of the PULSE the second cycle begins and so on, i.e. the time-
lag between the pulses is determined by the DELAY (x 0.01 ms) switch (#2, Figure 5).
