Displaying the results graphically
To display the measurement progress and the readings in the live chart view:
1. Press the [settings] key at the front panel.
2. In the "Functions" tab, select "Live Chart".
3. To configure a parameter for display:
a) Select a parameter softkey on the right of the screen.
The "Configure Chart Trace <n>" dialog opens.
Figure 8-14: Configure chart trace dialog
b) In the "Data Source" list, select the parameter, e.g. "Impedance (Z)".
c) Select a color for the parameter trace.
d) To show the minimum and maximum readings of the selected parameter, turn
"Show Min/Max".
e)
To show the trace, turn "Enable".
f) Confirm with "Apply".
4. Repeat step 3 to assign additional traces, e.g. to display the readings of the reac-
tance and phase angle.
5. Select an appropriate time scaling using the "+/-" magnifiers in the "nn s/div" soft-
key.
6. Select "Clear" to restart the trace display.
The graph shows the traces of the measured values for the selected parameters. If
enabled, the chart assigns the measured minimum and maximum readings to the
trace of the parameter and displays the values numerically.
