This item of menu Settings allows to vary the value of an analog output
during the performance of a series of measurements.
The button “Choose driver (variable an. output)” allows to choose the
driver of the device having the output to control.
After
having chosen this driver, if one or several functions stdead
exist (functions stdnead with length greater than 0), the name
of
this or these functions appears in the list on the left, and you can
choose the channel.
The check box “Take into consideration ?” must
be ticked so that the choice is effective; it is a safety measure: one
can choose a driver and a channel, and not activate it immediately.
The
function of transformation allows to control the value of this analog
output during the performance of measurement. Setting this output at
3.5 will fix this value at 3.5 during all the series of measurement; to
set it at xt will cause a progressive increase during all the series of
measurement, because xt is the time.
When these choices are
validated by button OK, nothing occurs (contrary to the choice of the
fixed analog outputs). This variable analog output will be effective
only during the performance of new series of measure, by Measurement |
Launch measurement !
