A time measurement runs in condition S1 = 0, i.e. with the button pushed. Another approx. 5 ms
are added to the waiting time of 5 ms for execution of a total of five commands in the counting
loop. Therefore, the time unit of the measurement is 10 ms.

Listing 5: Time measurement
Push the button S1 as briefly as possible. You will receive, e.g. the result 1010, i.e. decimal 10.
Since the time unit of the programme is 10 ms, the display means 100 ms. With a little training,
you can reach short times down to 50 ms.
7 Reading Programmes
For programming, you need the buttons S1 (data input, left) and S2 (programming, right). The
reset button is required as well. These buttons alone can be used to read programmes and enter
any programmes. With a little practice, you can enter new programmes very quickly and modify
present ones.
To enter programming mode, perform a reset with the programming button S2 pushed, and
release S2 only about half a second after the reset. Now you can use the button S2 to scroll
through the present programme and view the commands and data. Each address requires two
button pushes at S2 for this. This switches between display of the command and the data. The
current address is also briefly displayed.
