When you
Close
this box, your modifications will be saved, and will appear in the
Sample
Description
column for the
next
downloaded list. These descriptions can be modified again later as
your requirements change.
Copying values
To copy the results to the
Windows Clipboard
, so that the data can be pasted into a spreadsheet,
word processor or other Windows program that accepts tabular text information, choose the
Clipboard
command from the
Export
menu.
Saving values
To save this list of measurements as a text (
.txt
) file, capable of being recalled by the Hach 3658
program or imported as a file into other Windows programs, choose the
Save As
command from the
File
menu. A dialog box appears, with a space to fill in with an eight-letter name (the program
automatically attaches a
.txt
suffix to these files). If you have saved previous files, a grayed-out list of
these names appears as well. Typical to Windows programs,
Directories
and
Drives
boxes can be
used to locate other storage devices on which to save your data.
Printing values
To place this list of measurements into a tabular format and send it to the Windows printer, choose
the
command from the
File
menu. The program asks you to enter
Title
and
Author
information. Note that the
Date
is fixed by your operating system. The resulting printed list will
include this information on each page.
Clearing stored values
To clear all the values stored in the analyzer via the Hach 3658 program, choose the
Clear Data
command from the
Logger
menu. Since this action will clear the storage memory of the instrument, a
warning appears first. Choose
OK
to bring up the next dialog box to confirm the clear action. Choose
Clear
to start the memory clear operation. A message,
Reset should be completed
appears in this
box when the task is finished.
Note: You can accomplish the same thing passively, by simply allowing the analyzer to overwrite a set of stored
values with new ones.
Monitoring measurements in real-time
You may wish to analyze a particular sampling point via the Hach 3658 program's
Monitoring
menu.
To use this Monitoring chart, the instrument must be connected to your PC. Choose
Monitoring
from
the Hach 3658 menu to bring up a chart display.
The Monitoring chart shows the gas concentration (in blue), temperature (in red), and pressure (in
green) as the sample is being measured by the instrument. The chart is updated directly from
instrument measurements, at a rate determined by the time scale set in the
TIMEBASE
box at the
lower right corner of the chart.
Click the
TIMEBASE
up/down pointers to change the time scale of the divisions of the chart. Each
division mark along the baseline (1, 2, ...10) can be made to represent from 30 seconds to 2½ hours,
providing from 5 minutes to 25 hours of continuously displayed samples. The chart updating rate is
determined by the time scale selected.
