Averaging Over A Cycle - Ahlborn ALMEMO 710 Operating Instructions Manual

14. Wizards
Start
To set the averaging mode
To delete the average value automatically on start (s. 13.6.3)
or with function ´Delete average value´
To start averaging
Read out the actual measuring duration (s. 14.4.2.1)
To stop averaging
For a fixed averaging period there is the function
Read out average value in function
14.4.2.1 Actual measuring duration, fixed measuring period
For averaging over time (see above) and for many other measuring operations
the actual measuring duration, from start to stop, or a programmable fixed
measuring period is required. To continuously monitor the actual measuring
duration the function ´Actual measuring duration´ is provided; this has the
format ´hh:mm:ss.x´ and a resolution of 0.1 seconds; this is also used in the
process of data recording. (see 10.4)
If in the operating parameters the function ´Delete measured values on start of
measuring operation´ is activated (see XREF), the actual measuring duration
will also be deleted automatically on each start.
We are already familiar with the function ´Fixed measuring period´ from the
data logger. (see 10.4.2)
It is used to stop a measuring operation on expiry of a fixed period of time.

Please note that, for data recording, the function channel or fixed
measuring period, programmed here purely for test purposes, may
have to be deleted again !

14.4.3 Averaging over a cycle

To acquire average values at cyclic intervals using the output cycle the averag-
ing mode ´CYCL´ must be set. This mode ensures that on completion of each
cycle the average, maximum, and minimum values are displayed and output
via function channels to memory or to the interface and are then deleted.
