Real-Time Clock
The time shown on the recording display is linked to the logger’s internal real-time
clock.
A day change occurs when the display time rolls through midnight (i.e. 00:00), which
triggers the statistical data to be finalized for the day, and a new day to be started when
the next reading is taken.
Each time the logger is configured with Control Solutions VTMC the display clock value
is set to the PC's current local time (or timezone).
Note that the logger’s internal real time clock value is only updated when the
recorder is configured with Control Solutions VTMC. This prevents the data
logging becoming discontinuous, which would be the case if the real time clock
were to be changed together with the display clock.
Control Solutions VTMC can display the logged readings in a number of different time
zones, regardless of where it was configured.
Manually adjusting the time zone
The clock shown on the display of the logger can be adjusted in 15-minute steps so it
displays the time in the current local time zone. This can be done directly on the unit,
using the buttons. It is particularly useful when you want to adjust the time for daylight
saving but you do not wish to re-configure the unit.
You cannot adjust the time zone
l
when the logger is
STOPPED
;
l
when the logger is connected to a PC via USB;
l
when the logger has been started, and is counting down during a delayed start; or
l
when the logger has been configured for a date/time start, but has not yet started
logging.
If you adjust the time zone, the times that are reported on the PDF and in the software
will reflect this change.
