5.2.2.6 Performing Limit Checks
Limit checks allow you to analyze the measured values. If the defined limits are exceeded,
specific actions can be initiated. Margins are not as strict as limits and belong to the valid
value range, but can also initiate certain actions. Limit checks are available for all auto-
matic measurement types.
To perform a limit check
1. From the "Meas" menu, select "Setup" to open the "Measurement" dialog box.
2. Select the tab for the measurement you want to configure.
3. Under "Limit check", select "Limit only" to distinguish only between valid and non-
valid values, or "Margin&Limit" to perform a two-level value check, where the margin
is still valid, the limit is not.
4. In the measurement overview, define the upper and lower limits and, if selected,
margins for each active measurement type to be checked.
5. In the measurement overview, define the valid value range for each active measure-
ment type to be checked. Note that the margins must always be within the valid value
range. If necessary, the limit or margin values are adapted to match the selected valid
range.
For details on the value range definitions see "Limit check" on page 160.
6. Define what happens when the limits and margins defined for a measurement type
are exceeded.
a) Select the "Event Actions" tab.
b) For each action, define whether it is to be initiated:
● if the limits or margins are exceeded
● if the measurement is completed without limit violations
● not at all
c) If "E-mail" is selected, define a recipient address under "E-mail setup".
If "Save Wfm" is selected, define a storage location under "Waveform destina-
tion".
If "Print" is selected, configure the print settings as described in chapter 12.1.1,
"Configuring Printer Output and Printing", on page 344.
As a result of the limit check, the specified actions are performed and the status is
indicated by an icon in the result box (see chapter 5.2.1, "Measurement Types and
Results", on page 129).
