Toggling between the channels
If the measurement is started on several channels, the display of the measured values can be adapted as follows:
AutoMux mode
If the AutoMux mode is activated, the measured values of all activated channels (measuring and calculation channels) are
displayed consecutively. The next active channel is selected after 3 s. The toggle time can be changed in the menu item
Special functions\Dialogs/Menus\Toggle time.
HumanMux mode
The measured values of one channel are displayed in the HumanMux mode. The measurement on the other channels
continues.
• Press to display the next activated channel. The measured values for the selected channel are displayed.
Each measurement starts in AutoMux mode. Press to toggle between the modes.
Status line
Important information of the running measurement is summarized in the status line. The quality and precision of the
measurement can be evaluated. Press during the measurement to scroll to the status line.
