Error Messages
This screen monitors any interruptions in unit function. The unit saves and organizes
errors by the type of error and the date and time at which the error occurred. The
ALT key deletes error messages one at a time, from the latest to the oldest.
Deleting an error message before it has been addressed will
prevent it from being written to memory again. However, the error
will surface in the memory once it occurs again (or if the power
supply is briefly interrupted).
Trend
This display functions like an electronic logger. It records average readings at a
designated interval for depth, average flow velocity, and depth (level) for the past 90
days. The user can select and view individual values from a submenu.
Figure 8-9 Trend value selection
The period over which the values have been averaged displays at the bottom of the
screen. New values are added as vertical lines on the right-hand side of the display at
the end of each configured storage interval (Figure 8-10). As new readings display,
older values move to the left and eventually move into the internal memory.
Use the left/right arrow keys to scroll through the time intervals to view older data
sets. Browse through daily values using the up/down arrow keys. This enables the
user to calculate and evaluate previous measurements, trends, dry weather periods,
and possible measurement problems that may have occurred in recent days.
The internal memory has a 90-day capacity. Therefore, new data will overwrite older
data sets in memory.
Scrolling will scale the readings displayed automatically; therefore, these values may
change to represent the most accurate reading available.
The user can set the time interval for the memory in the PAR > Storage Mode >
Interval menu. The factory default setting is a 2-minute interval.
