# Tightening Program Properties

## General Settings

Parameter | Description
--- | ---
Name | A user-defined name for the multistep program.
Thread Direction | Direction of the threads, either clockwise or counterclockwise
Program Start | Sets the torque level for generating a result. If left blank, the result is generated every time the tool is started; otherwise result is only generated from the set torque level.

## Trace Configuration

The trace configuration can be done on program level or for each step. The default configuration is set on the program level and can be overridden in each step as needed.

Here, enabling this function allows the configuration to be done on program level.

Parameter | Description
--- | ---
Enabled | On: Enables the trace resolution configuration on program level. Off: The trace recording is done with the same resolution for the whole tightening. In this case, the trace points are evenly distributed in time over the whole tightening. For each time slot (1 ms) two values (the minimum and the maximum measured value) are displayed in the trace. The maximum number of samples in this format is 2000.
Sample Time | Choose the sample time from the drop-down list (1 - 1000 ms).

With this trace recording the sample rates will not be 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.

The maximum number of samples in a trace is 4096.

If a tightening produce more than 4096 values a down-sampling will take place. This is done by removing every second trace sample from the whole tightening and when continue the recording with half the resolution. This process will be repeated every time the 4096 sample limit is reached.

If more than 2048 in total was recorded, this process will result in a trace between 2048 and 4096 samples.

If the limit if 4096 samples is reached the configured trace sample times will no longer be followed. Instead the sample times will be doubled or quadrupled etc., depending on how many times the down sampling has taken place. Since all steps are down sampled the relation between the steps will still be the same though. If a step was configured with double sample time compared to another step, this will still be the case in the final trace regardless how many times a down-sampling has occurred.

If more than 4096 samples is recorded, the configured trace sample times will no longer be followed. Instead the sample times will be doubled or quadrupled, etc., depending on how many times the down sampling has taken place. Since all steps are down sampled the relation between the steps will still be the same though. If a step was configured with double sample time compared to another step, this will still be the case in the final trace regardless how many times a down-sampling has occurred.

## Validation

During the configuration of tightening programs, the entered values are compared with the tool capability values to prevent parameters being outside the selected limits. User-defined maximum values are useful if many different tools are being used.

Parameter | Description
--- | ---
Validate against tool values | On: entered values are compared with the tool capability values. Off: no validation performed.
Tool | Shows the tool to compare the values with.
Max Torque | Allows the user to compare the values with a simulated tool.
