Decisions

Results from a measurement can be compared against minimum and maximum thresholds to generate pass / fail decisions. The decision state is pass if a measurement value is between the minimum and maximum threshold. In the data viewer and next to the measurement, these values are displayed in green. Otherwise, the decision state is fail. In the user interface, these values are displayed in red.

All measurements provide decision settings under the Output tab.

Value (14.785) within decision thresholds (Min: 14, Max: 15). Decision: Pass

Value (1604.250) outside decision thresholds (Min: 1500, Max: 1600). Decision: Fail

Along with measurement values, decisions can be sent to external programs and devices. In particular, decisions are often used with digital outputs to trigger an external event in response to a measurement. See Output for more information on transmitting values and decisions.

To configure decisions:

1. Go to the Measure page by clicking on the Measure icon. The scan mode must be set to the type of measurement you need to configure. Otherwise, the wrong tools, or no tools, will be listed on the Measure page.

2. In the Tools panel, click on a tool in the tool list.

3. In the measurement list, select a measurement. To select a measurement, it must be enabled. See Enabling and Disabling Measurements for instructions on how to enable a measurement.

4. Click on the Output tab. For some measurements, only the Output tab is displayed.

5. Enter values in the Min and Max fields.
