EFFECTS ON THE RUNNING TIMEBASE DISPLAY

The timebase display in Monitor mode no longer counts up time from start of cycle after the system starts to loop. Once it passes the point from which it must loop back, it displays the time flow within each loop. Once it has finished looping it continues to count up time from the beginning of the last loop.

The need for calculation can be removed by changing the basis of timing to a segmental one, but it is no panacea. However, if you would like to explore this system variant please contact Service Dept or your dealer.

NESTED LOOPS

The following shows an example of the use of nested loops. When this program is run it causes the temperature to return to 25°C (point 8 in the diagram) at 9 minutes 40 seconds after the start of the cycle, not at 2 minutes 20 seconds as listed.

CALCULATION FOR SUCCEEDING EVENTS

event statement time = event actual time - total looping time

The "total looping time" is the time to execute the loops as defined by LS & Rep.

In the above example it comprises:

(segment 2 is the first segment looped back TO)
