that you enter the full-scale value for the condition being plotted.
For example, if you selected LEVEL as a condition, the following
would appear:
The flow meter automatically goes into over-range if the data
goes higher than the full-scale value you have selected. You can
easily recognize over-range operation by the plotted line running
off the right side of the chart and then immediately reappearing
on the left side of the chart. Because of the over-range feature,
you can set a full-scale value that gives you good resolution on
the chart. At the same time, the automatic over-range will
prevent the loss of recorded data if the plotted line rises past the
full-scale point. For the other conditions, the full-scale units will
be appropriate for what is being measured (D. O., pH, temper-
ature, etc.) The flow meter is capable of multiple over-ranges.
(TEMPERATURE), (YSI pH), (YSI D.O.), (YSI SALINITY), and
(YSI TEMP) may also appear. Again, as for line A, you can select
another condition to plot on the chart. The flow meter will again
request a full-scale value. The full-scale value can be different
from that of line A.
(TEMPERATURE), (YSI pH), (YSI D.O.), (YSI SALINITY), and
(YSI TEMP) may also appear. For line C, you can select yet
another condition to plot on the chart. The flow meter will again
request entry of a full-scale, or bottom and full-scale value.
You must have an Isco Rain Gauge or equivalent connected to the
flow meter to measure rainfall. Output is recorded in either
inches or millimeters. There is only one over-range for rainfall.
2.4.12 Step 9 -
Reports/History
Go to step 9 and the following display will appear:
This step lets you set up the flow meter to print periodic reports.
The typical report contains such information as the period of
time covered in the report, maximum and minimum levels, and
when they occurred. You can define two different reports in this
step. For example, this is used to provide weekly and monthly
reports. You can choose the content of the reports by working
through the menus in
step 1 .
