Measuring Time Measuring time of a cycle in seconds.
Cycles The cycle parameters for all measurement modes are defined
in this menu:
One defines whether
the measurement is to be performed once (setting: 1)
the measurement is to be repeatedly constantly (setting 0)
a predefined number of cycles is to be performed (setting
N, where N can be between 2 and 9999).
Preset Acc. (%) Once the accuracy of the measurement is less than the preset
accuracy, a measurement cycle is stopped even if the preset
measuring time has not yet been reached. If there are two
measuring channels (e.g. alpha and beta channel), the meas-
urement cycle is stopped as soon as both accuracies are below
the two preset accuracies. If you want to stop a measurement
via the preset measuring time, you have to enter a very small
value for the preset accuracy to make sure it will never be
reached, for example, 0.01%.
