The data is stored in comma-delimited text files. These
files can be opened with text-editing software (e.g. Micro-
soft Word) or spreadsheet software (e.g. Excel).
The first two lines of the data file give the logger’s name
and serial number. The third line indicates that latitude
and longitude are referenced to the 1984 World Geodetic
Survey datum. The fourth line shows the cone index unit
system. The fifth line shows the column headings for the
rest of the data file. Each row of data represents a meas-
urement profile.
Logging sessions are started and completed by turning the
meter on and off. The start of a logging session is indi-
cated by the data line “Logger Started”. If a GPS signal
was found at the start of a logger session a time stamp is
included on the “Logger Started” line.

Communications Port to
which the PC-3.5 serial
cable is connected can be
identified by using a
paper clip.
1. Disconnect the serial
cable from the meter.
2. To bring up the Port Selection screen, click on the
Com Port Button, select the com port to be tested and
click the Port Test button. Click the Test Port Now
button. If the message “Connection OK” is displayed,
another device (such as a modem) is probably connected
to that port. If the message “No Connection” is displayed,
this port may be the one connected to your serial cable and
you can proceed to the next step.
3. Place a paperclip on the end of the serial pin so that it
touches both the tip of the pin and the metal area between
the two black rings. Again click on the Test Port Now
button. If the message “Connection OK” now appears,
this is the com port connected to your serial cable.

while the meter is connected, the “No Connection”
message will be displayed.
