Do you want embedded data fields or the value of the unselected sliders set to zero?

Simin
You can include 4 embedded data with a hardcoded value o '0' in it e.g.: ED1=0.
And at the end of survey or after block just update the embedded data via a branch logic something like this for all 4 sliders:
The one's which have the value of 0, the respondent may have selected 0 or might have not slided the slider.

Hope this helps!

Great job on providing a solution Deepak along with screenshots!

TomG I want to set the value of the unselected sliders to zero.

Qualtrics.SurveyEngine.addOnPageSubmit(function() { 
jQuery("#"+this.questionId+" .ResultsInput").filter(function(){return this.value.length==0;}).val("0").trigger("change");
});
