This function could be triggered automatically at preset threshold value or manually as you choose, and the triggering mode and record duration can be configured in the Setting mode of Live Data.
Freeze – displays the retrieved data in freeze mode.
* Previous Frame – Moves to the previous frame in the freeze data.
* Next Frame – Moves to the next frame in the freeze data.
* Resume – this button appears when the Record or Freeze function is applied. Tapping this button stops data recording, or exit freeze data mode, and resumes normal data display mode.
* Flag – this button appears when the Record function is applied. Tapping this button sets flags for the recorded data at points wherever you choose, when playing back the recorded video clip later in Data Manager, the
preset flag will enable a popup to allow input of text to take notes.
* Clear Data –tapping which clears all previously retrieved parameter values at a cutting point whenever you choose.
* To Top – moves a selected data item to the top of the list.
* Graph Merge – tap this button to merge selected data graphs (for Waveform Graph Mode only). This function is very useful when making comparison for different parameters.
NOTE: This mode supports Graph Merge for 2 to 3 parameter items only, so select no less than 2 or more than 3 items each time when making graph merge.
* To cancel Graph Merge mode, tap the drop-down button on the right side of the parameter name, and select a data display mode. Show Selected/Show All – tap this option to exchange between the two options; one displays the selected parameter items, the other displays all the available items.

Active Test
The Active Test function is used to access vehicle-specific subsystem and component tests. Available test vary by manufacturer, year, and model, and only the available tests display in the menu. During an active test, the tester outputs commands to the ECU in order to drive the actuators. This test determines the integrity of the system or parts by reading the engine ECU data, or by monitoring the operation of the actuators, such as switching a solenoid, relay, or switch, between two operating states.
Selecting Active Test opens a menu of test options that varies by make and model. Selecting a menu option activates the test. Follow all screen instructions while performing tests. How and what information is presented on the screen varies according to the type of test being performed. Some toggle and variable control tests display Active Test Controls at the top of the screen with data stream information below, or vice versa.
