F2 – 12/24 Hour Format
Use function F2 to apply a 12 or 24-hour format to the time output by:
• “keypad Interface” on page 25
• “F8 – Continuous Time Once-per-Second” on page 42
• “F9 – Time On Request” on page 44
• “F90 – Code Output Configuration” on page 72
F2 affects how all four types of time (Local, Standard, UTC, GPS) appear when displayed or output.
The 12-hour format counts hours from 1 to 12 twice per day, like a conventional wall clock. The 24-hour
format counts hours from 1 to 24 once per day. For example, in the 24 hour format, 18:00 is equivalent to
6:00 PM in the 12-hour format (i.e., 18:00 – 12:00 = 6:00 PM).
