I am not sure I understand but Normal test will work for Normal data (can be positive, 0 or negative). Delta normal test is special case where your data contains some part of normally distributed data plus many zeros. Like a combination where you have some zeros (e.g. non conversions) and some normally distributed data.
From the first look Normal test will not work. Will Delta Normal test work with negative and zero values?
