With the interaction number feedback, values from measurement processes can be recorded easily. In the same step these are compared with the target value and its defined tolerance limits. The tolerance is determined by selecting one of the four tolerance types – exact, relative, percentage or absolute – and the respective values.
Create a number feedback
First click on the interaction button on the right side above the process steps and then select the interaction type Number Feedback.
Nominal value, unit and accuracy
Set the nominal value first. It is also possible, to determine whether the associated target value can be seen, when the actual value is asked or whether it remains hidden for the user. Additionally, you can define the required precision for the requested value.
There are four options, on which tolerance type you can measure your number against. The following four options are available:
Exact - no tolerances: The actual value should match the target value without deviation.
Relative tolerances: The tolerance limits are set in relation to the target value.
Relative percentage tolerances: Definition of the permissible deviation up/down in percent.
Absolute tolerances: Definition of the permissible maximum and minimum values.
Important: If you want to have NO Tolerances at all, choose the absolute tolerance and leave the tolerance fields free. This makes sense for a simple measurement, where you just want to make sure, that only numerical values are entered by the user.
Set tolerances visibly
In addition, this interaction can be used to define whether the entered tolerance values are visible to the subsequent user and whether error messages occur in the report if the upper or lower tolerance limit is exceeded or undershot. For this, you must activate the fields visible. If you activate the fields failed if more or failed if less, the report is considered faulty if the upper or lower tolerance limit is exceeded or not reached.
The number feedback in the Assistant
View with visible target value and tolerance limits
The tolerance limits are marked red, if the entered value is above or below the tolerance limits and a warning message appears.
The tolerance limits are marked green, if the entered value is within the tolerance limits.
