User’s Guide
The result of a time period measurement with time discontinuity caused by internal
buffer overflow is displayed in red color, or as a string followed by “!” character. This
indicates, that the displayed time is not correct.
If the time break is caused by ARM-ing the data acquisition, the time can be
reconstructed and there is no difference between displaying the result of
measurements with no time discontinuities and with time discontinuities caused by
ARM-ing.

If more than 1 sample is displayed to one dot of the waveform, it is necessary to set
the mode of creating the dot. There are two buttons to choose the basic mode.
If “SNG” is selected, only the first sample of time period represented by the
dot is displayed.
If “Calc” is selected, the dot is calculated out of all samples. The method of
calculation depends on the following controls:
If the is activated, the displayed dot is calculated as average of the
measured samples.
If the is activated, the displayed dot is calculated as a maximum of
measured samples.
