The data logger has two modes of operation:
Com-
munication
and
Measurement
. These modes are
indicated by the
button at the
bottom of the keypad. When the but-
ton is flashing, the meter is in
Com-
munication
mode. When the button
glows steadily, the meter is in
Meas-
urement
mode.
Communication Mode
When the meter is turned on, it will be in
Communi-
cation
mode for approximately 10 seconds. While in
this mode, the PRINT button will flash. It is only in
this mode that a user can initiate a logger communi-
cation (download or reconfiguration). If communica-
tion between the logger and software is attempted
during this 10
-
second period, the logger will remain
in
Communication
mode indefinitely. The meter
must be turned off and then on to change to
Meas-
urement
mode (see following section).
Measurement Mode
Approximately 10 seconds after turning on the meter,
the PRINT button will glow steadily. This indicates
the logger is in
Measurement
mode. In this mode,
you can calibrate the meter and record data. When
you are finished collecting data, the meter must be
put into
Communication
mode by turning it off and
back on (see previous section). If you are collecting
data from several sites and need to turn off the meter
between data collection sessions, wait until the me-
ter transitions from
Communication
to
Measure-
ment
mode after turning the meter back on.
