You will need to observe the following rules while adjusting the time:
Internally, the logger always retains its clock in UTC. You cannot adjust the clock
l
beyond the allowed time zone limit of +15 hours and -12 hours from UTC (these are
the same values you see as allowed time zone values in Control Solutions VTMC
during configuration).
For example, if 13:25 is the currently displayed time, and the logger is configured
with Hawaiian time zone (-10h when in daylight saving), the earliest time would be
11:25 (-12h).
You cannot adjust the time across midnight.

You will hear three short beeps if you try to increase or decrease the time zone
l
beyond the allowed limit.
An inspection mark is placed in the logged readings, regardless of whether you
l
adjusted the time zone or not.
You cannot use the time zone adjustment to correct small errors in the displayed
l
time. To do this, please re-configure the unit with Control Solutions VTMC.
