6.4.4 Averaging over Cyclic Measuring Point Scans

Continuous averaging

Again, the averaging mode ´CONT´ must be used if the average value over the
whole measurement is only required at the end of cyclic meas. point scans.

Setting the averaging over all measuring point scans:

Averag.Mode:   CONT

Programming the print cycle (see 7.2):

       

PrintCycle:00:15:00 U

Automatic clearing of average val. on start (see 10.8)
or, after selecting the average value, by using:

Cyclic averaging

The averaging mode ´CYCL´ must be used if average values have to be
acquired in cyclic periods over these periods. This ensures that the average
values are cleared after each print cycle. Furthermore, either the continuous
measuring point scan or a measuring cycle must be activated to obtain
measured values within the print cycle for determining average values.
 

Setting the averaging over cycles:

Averag.Mode:   CYCL

 

Programming the print cycle (see 7.2):

PrintCycle:00:15:00 U

Switching on the continuous measurement:

    ConvRate:  10 Cont: 

"

or programming the measuring cycle (see 7.2):

Meas.Cycle:00:00:30 U

For recording the average values an additional 

function channel

 with the

range M(t) (see manual 6.3.4) or the corresponding 

output function

M(t) (see manual 6.10.4) is required instead of the measured value.
