Data Logger Operation - Spectrum Field Scout EC 450 Product Manual

Data Logger Operation

The data logger has two modes of operation: Com-
munication and Measurement. These modes are
indicated by the PRINT 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-
PRINT button
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.
