tell when the printer is in over-range if a data line goes off the
chart on the right side and then immediately starts over again
plotting on the left side.
2.3.9 Step 9 -
Reports/History
This step lets you program the flow meter to print out regular
reports on the internal printer. The reports the flow meter prints
are a summary of activity the unit records over a period of time.
Typically included are such items as maximum and minimum
flow rates, the time they were reached, sample records, etc. The
flow meter lets you create two separate reports, and lets you
define what appears on them to a great extent. Note that the con-
tents of the reports are defined in Setup in
step 1 . Step 9 merely
lets you turn them off and on and set the timing. You can define
the start time, the interval between reports and other aspects of
the report.
History provides a record of changes made to the flow meter’s
program or operation events. As many as 50 changes can be
stored in the flow meter’s memory at a time. The memory can
store up to 50 history items and 200 sample events at a time.
2.4 Interpreting the
Program Screens
Following are the program screens as they appear on the display
of a 4250 Flow Meter. Explanations of most of the screens will be
provided.
Note
Some items that appear in the menus have parentheses (...)
around them. This means that the item may or may not appear
on your flow meter. Choices made from the beginning of the
program will make some options unavailable later.
An example of this is the pH/D.O. option. Selection of one in
Step 1 will keep the other from appearing in all following
menus.
This list does not include all possible screens for the unit, but
does cover the screens found in a typical programming
sequence. Some diagnostic and error screens are covered in
Section 5.
