From your Freshping account's dashboard, open the Check's menu, represented by three vertically stacked dots.

• Click 'Edit Check’ to open the Edit Check page
• You’ll find the ‘Location Settings’ listed under 'Advanced monitoring settings.
• Choose a location from the list given
• Click 'Save' at the bottom right corner
  

Monitoring location can also be configured while creating the Check in the same way.

Your check will be monitored from the location that you have chosen. You cannot change location preferences from all the checks that you monitor at once. You have to change the preferences for each check individually.
