4220 Flow Meter Section 2 Programming
2.4Interpreting the Program Screens
2.4.1 Operating Mode
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.
Following are the program screens as they appear on the display of a 4220 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 6.
Turn on the machine. Wait for the display to settle. Then press the Enter/Program Step (Enter) key. The following will appear. (Step 1) If the following menu does not appear, press Exit Program, then Go To Program Step, then press 1.
