reading/readings?

The 3 numbers (hours, minutes, seconds) in the three separate fields make a countdown time value (such as 1:29:00). The numbers are in three separate fields, not in one field. I need to describe the data. Should I call the 3 numbers in the 3 fields together as a reading, or call them 3 readings?
The numbers are in three fields, not in one, because they could be changed separately if necessary.

Call what a reading? Or readings?
Please give us the full sentence in which you want to use reading or 3 readings

Should you call what a reading? What part of the text do you want to consider calling a reading/readings? Please clarify. Thank you!
