Thereby, the unit simultaneously records the mean and the min-max
values of:
• LEVEL RMS and
• THD+N and
• Frequency
The curves of these measurement functions are stored in individual
graphs. Within a graph, every sample is represented by a single dot
only, thus building the displayed curve.
In practice, the following steps are required / available for the execution
of a time sweep:
• To enter the time sweep mode, select the entry SWEEP → TIME
in the measurement function submenu.
• If required, activate a filter through the corresponding menu.
• To select the curve to be displayed (LEVEL RMS, THD+N or
Frequency) move the cursor to the curve entry, press enter key,
use the arrow keys and confirm with the enter key.
• To select the mean / min-max mode, move the cursor to the
corresponding field, press enter and the arrow keys.
The curve and the mean/min-max mode can also be
selected after the sweep recording is completed.
• Move the cursor to the REC field and press enter.
