2.14 Step 8 - Printer This step sets up the operation of the flow meter's internal
printer. This printer also functions as a plotter. The
printer/plotter is capable of printing alphanumeric information
(words and numbers), and at the same time, plotting linear data
like flow, level, pH, etc.
The unit can print as many as three different data lines while it
regularly records other printed information supplied from the
flow meter. Program selections made in this step will determine
the appearance of the printer/printer's chart.
The first menu will request the speed of the chart.
If you select OFF, the printer will be disabled. No data will be
printed on the chart. The flow meter will, however, still print
reports if you activate that function in step 9. The choice made
from the other speeds depends on the amount of data you need to
record on the chart.
If you are recording from a relatively stable situation, are using
only one data line, and you want to achieve maximum longevity
for the chart paper roll, select a lower speed for chart advance.
On the other hand, if there is a great deal of activity in your
installation, and you must use all three data lines, selection of a
faster chart speed will probably produce a chart more easily read
and interpreted.
After you select the printer speed, the flow meter will ask you to
define what input you want depicted by printer LINE A. (The
printer can print as many as three separate data lines at the
same time.) The following display will appear:
(TEMPERATURE), (D.O.), (YSI pH), (YSI D.O.), (YSI CONDUC-
TIVITY), and (YSI TEMP) can also appear. Remember that
menus in parentheses may or may not appear due to previous
program selections. Either pH or D.O. may appear, but not both.
The various YSI options will only appear if you have enabled the
YSI 600 option in step 1, previously. You must have the appro-
priate probes to sense these conditions for the flow meter. Select
OFF, if you do not wish to use this line.
If you select pH, D.O., TEMPERATURE, or any of the YSI
options the flow meter will request that you set limits that will
serve as the bottom of the chart and the chart full-scale.
You would enter here the lowest pH value you expect to see in
your flow stream:
