The following time line illustrates the three variables, with case B in mind. Sampling takes place within the time
periods marked gray.
The sample interval always starts, as far as possible, at an even time -- for example, if the sample interval time is
one hour then the sample intervals start on the hour. The sensor outputs are sampled throughout the sample
duration time.
A wide range of sensor sampling schemes are available from the WEATHERPAK. Examples are:
the sensors can be sampled continuously, with no gaps; the WEATHERPAK can take samples from ten past until
half past each hour.
Inspecting Raw Data
The Test Menu lets you inspect raw data as it is measured -- without any averaging or other processing. The data
can be inspected either before or after conversion to engineering units. Enter
T
from the user menu to reach the
TEST
Menu.
TEST MENU
(R) Display Raw Sensor Data (H) Help
(S) Display Scaled Sensor Data (U) User Menu
(Q) Quit
You cannot change anything from the Test Menu.
R
Display
RAW
sensor data. The terminal will display, as it is measured, raw data from each sensor. The
values are displayed before conversion to engineering units -- for example, volts for analog sensor inputs.
S
Display
SCALED
sensor data. The terminal will display, as it is measured, scaled data from each sensor --
in engineering units.
Exiting the User Interface Mode.
The WEATHERPAK continues to collect data while you are in the User Interface mode. If there is no terminal
activity for approximately five minutes, the WEATHERPAK will time-out, exit the User Interface mode, and
resume displaying the data sample lines
.
To manually exit the User Interface Mode, select
Q
to
QUIT
from any
menu.
