F11 – Time Output Format
Use function F11 to review or change the format of the time output string used in F8 and F9. The as-
shipped factory setting for F11 format is null, which enables F8’s and F9’s default time output formats.
The default format for
F8 – Continuous Time Once-per-Second is:
<SOH>DDD:HH:MM:SSQ<CR><LF>
Note:
F8 does not display milliseconds, regardless of the format defined in F11.
The default format for F9 – Time On Request is:
<SOH>DDD:HH:MM:SS.mmmQ<CR><LF>
where:
The time quality character, “Q”, is one of the following characters:
See “F5 – Time-Quality Setup” on page 39 and “F13 – Time Error” on page 48 for more information.
When the unit responds to “F11<CR>” with the current format string (as shown in the following example),
the first character after the “F11” is a blank separator; it is not part of the format string.
<SOH>
= ASCII Start-of-Heading character.
<CR>
= ASCII Carriage Return character.
<LF>
= ASCII Line Feed character.
DDD
= Day-of-year.
HH

MM

.

:
= Colon separator.

.
= Time error has exceeded time quality flag 1’s threshold
*
= Time error has exceeded time quality flag 2’s threshold
#
= Time error has exceeded time quality flag 3’s threshold
?
= Time error has exceeded time quality flag 4’s threshold
