In the mode "Fixed Limits" of the tolerance range monitoring of a ToolScope, the distances between the limits and the signal can be defined. This procedure offers significantly more configurable parameters.

Configuring the fixed monitoring procedure

 

Configurable parameters

Function name

Description

Activate offset compensation

The "Activate offset compensation" point can only be selected if the checkmark next to "Compensate signal offset" is set under "Service / Settings / Monitoring / Channel 1". If this function is activated, the respective signal is set to zero when measuring starts. This is helpful when there is a fluctuating base load, as false alarms are avoided.

Deactivate tolerance ranges

If this function is activated, the green tolerance ranges are hidden. This is useful if you have redefined your monitoring under Maximum value / Wear limit / Missing limit.

Distance to upper limit

This value specifies the distance between the upper limit of the tolerance range in the Y direction and the signal (see Mark 1). The value always relates to the distance that the monitoring would set by itself. A value of "1" causes the automatically calculated value to be applied exactly. Larger values increase the distance. Smaller values reduce it.

 

Distance to lower limit

This value specifies the distance between the lower limit of the tolerance range in the Y direction and the signal (see Mark 2). The value always relates to the distance that the monitoring would set by itself. A value of "1" causes the automatically calculated value to be applied exactly. Larger values increase the distance. Smaller values reduce it.

Delay time after the start of the process [s] / Delay time before the end of the process [s]

These values specify the time range after the start or before the end of the process, during which the monitoring should not calculate any limits (see Marks 3 and 4). If both values in this field are set to "0.0", both parameters are ignored.

Safety distance from the signal in the X direction [s]

This value specifies the distance between the limits and the signal in the X direction (see Mark 5).

Relearn; number of processes

As soon as the checkmark is set next to "Relearn; number of processes" and the process is observed the next time, the monitoring forgets the previous data and relearns the newly entered number of processes.
