Time/Date
The P-T
RAK
® particle counter has an internal clock that keeps track
of the time of day and the date. The format is HH:MM:SS where
HH is the hour in 24-hour format, along with minutes and seconds.
It is very important for the P-T
RAK
® particle counter to have the
time and date correctly set; otherwise, time and date stamping of
recorded data will not be correct.
The time clock is set correctly at the factory (for U.S. Central
Standard Time). If it requires adjustment, it may be changed by
selecting TIME/DATE from the Setup menu. The following screen
is displayed:
-TIME/DATE-
USE <> FOR POSITION
USE ^

FOR VALUE
HH:MM:SS 08:25:32
MM/DD/YYYY 11/02/2008
Figure 3-10: Time/Date
When first entering this screen, the first character in the hour (HH)
field will have a cursor underneath it. Use the up/down arrows to
increment and/or decrement values. Use the left/right arrows to
move to the required field. When all adjustments are complete,
press the “
↵ ” key to accept the changes and return to the
Setup menu.
