C. WRITE button:- Saves all the transformer data to Flash Drive.
D. Si.No:- You can edit the Serial Number of Transformer being tested.
E. CR:- Shows and edit the Calculated Ratio (can be edited by user before testing starts).
F. RECALL:- The Saved data (upto 500) can be seen on the ATRI-3F display.
