Change:

181   String offset_line = String((2.0 * v_div) / 1000.0 - offset) + "V";
203   String offset_line = String((2.0 * v_div) / 1000.0 - offset) + "V";

to:

181   String offset_line = String((3.0 * v_div) / 1000.0 - offset) + "V";
203   String offset_line = String((3.0 * v_div) / 1000.0 - offset) + "V";

to display the center line correctly.
