PVS5120-Series Portable Samplers
11
The
Clock
tab is only available when the user first connects to the VSC100 via
DevConfig
. After the user clicks on a tab within the
Settings Editor
screen,
the
Clock
tab will no longer be available.
The
Clock
tab displays the Reference (computer) Time, Station (sampler)
Time, and Difference (reference time – station time).
The
Reference Clock Settings
allows the user to choose if the reference clock
is running in Local Daylight mode or UTC (Greenwich Mean Time).
Click
Set Clock
button to sync the clocks (FIGURE
).
The clock must be synced before deploying the sampler if
running the sampler using
Stand-Alone, Time-Based
control or if a new operation system has been loaded to the
VSC100.
The sampler clock can have up to 1 minute of drift per month when running at
roughly 25 °C. If it is running at the extremes of the temperature range, the
user could see up to 8.2 minutes of drift per month between the VSC100 clock
and the reference clock. When the sampler is triggered via a datalogger, this
drift isn’t as critical since the datalogger clock may be more precise or sync on
a more regular basis. If running under
Time
control type, the clocks should be
synced whenever the sampler is serviced or the bottles collected.
