If you stored the first value as sample
001
, the instrument automatically increases the next
storage location, and labels it sample
002
. You can increase or decrease this number by pressing
the
Up/Down Arrow
buttons. If you label a sample number the same as a previously stored
measurement value, the new measurement value overwrites the previously stored value.

5.4 Storing and accessing measurements from a computer
If you have made measurements and stored them in the analyzer, you should be ready to bring them
into the Hach 3654 program for viewing, copying, saving and printing. Refer to
on page 18 for additional information on the Hach 3654 program.
5.4.1 Downloading stored values
To download the stored results from the instrument to the PC, choose the
DownLoad
data command
from the
Logger
menu.
The
DownLoad
window presents a display of the stored measurements from the instrument. The
window displays five columns of data:
• Sample (sequence number of the sample)
• Conc (concentration of the measured gas)
• Date (date of the measurement)
• Time (time of the measurement)
• Sample Description
The descriptions can be modified for your applications using the procedures described below.
5.4.2 Altering the sampling point descriptions
For help in identifying the locations of various sampling points that are stored by the instrument, you
may choose the
Sampling Point Description
command from the
Logger
menu to bring up the
dialog box.
The measurement values to be placed in positions 0 through 499 can be described however you
wish. Double-click on a particular position (or click
Modify
), then type a description in the box.
Choose
OK
when finished entering a description.
When you
Close
this box, your modifications will be saved, and will appear in the

, 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.
5.4.4 Saving values
To save this list of measurements as a text (
