7.8.3 Multiple measurement
A multiple measurement consists of a series of drift or time-controlled indi-
vidual measurements. For the measurement acceptance of the individual
measurements the same parameters as for the above-mentioned standard
measurements are decisive. Each entry in the measuring point list is a
'smoothed' value.
The data recording parameters determine the measuring series run. The
number of measurement cycles and the measuring interval determine the
time taken for the series of measurements. The measuring interval defines
the time pattern at which the individual measurements are triggered. De-
pending on the type of measurement acceptance and the stability of the
measuring signal the time at which the measurement is entered into the
measuring point list may differ from the time pattern.
It is very important that the waiting period for the measurement acceptance
is selected to be shorter than the measuring interval, i.e. the waiting period
for the individual measurements should have safely elapsed when the next
measurement (according to the measuring interval) is started.
