Data Logger Operation - Spectrum Technologies Fieldscout 2120 Product Manual

Data Logger Operation

The data logger has two modes of operation: Com-
munication and Measurement. These modes are
indicated by the green LED in the lower left corner of
the meter. When this light is flashing, the meter is in
Communication mode. When the light glows stead-
ily, the meter is in Measurement 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 green LED will flash. It is only in this
mode that a user can initiate a logger communication
(download or reconfiguration). If communication be-
tween the logger and software is attempted during
this 10-second period, the logger will remain in Com-
munication mode indefinitely. The meter must be
turned off and then on to change to Measurement
mode (see following section).
Measurement Mode
Approximately 10 seconds after turning on the meter,
the LED light 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 be-
tween data collection sessions, wait until the meter
transitions from Communication to Measurement
mode after turning the meter back on.
