# Trace Setting

When the trace configuration is enabled on the program level, the trace resolution can be configured on step level. The setting for Trace Setting defines how the sampling should be done on each specific step.

With this trace recording the sample rates are not the same in all the steps, instead the sample rate depends on the configuration in each step. This means the trace is divided into one trace for each step.

Parameter | Description
--- | ---
Trace Setting | Program: Use the settings as defined on program level. Manual: The trace sample type from the program level will be used, that is, Time or Angle. Using a different sample rate will override the setting on the program level.
Sample Time | Choose the sample time from the drop-down list (0.25 - 1000 ms).
Sample Angle | Choose the sample angle from the drop-down list (0.25 - 20 degree).

The maximum number of samples in a trace is 4096. If a tightening produces more than 4096 samples a down-sampling process will take place. A down-sampling process is removing every second trace sample from the whole tightening and continuing recording with half the resolution. This process is repeated every time the 4096 sample limit is reached. Since the down-sampling process is done for all steps, the relation between the steps is the same.
