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 Print 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.
