Gps Connection - Spectrum Technologies Fieldscout 2120 Product Manual

GPS Connection

The data logger searches for a GPS signal when the
meter is powered up. If a signal is found, latitude
and longitude values will be added to the data file. If
a GPS signal is not found when powering up, the
meter will not search for it when taking readings. If
the meter is turned off and back on, it will again
search for the GPS signal. Be sure the meter is in
Measurement mode (see p. 4) before taking any
readings.
When taking a geo-referenced data measurement,
the LED will turn off while collecting the GPS signal.
The meter is again ready to take a reading when the
LED returns to a steady glow. If the data logger
loses the GPS signal, the LED will flash briefly be-
fore returning to Measurement mode. In this case,
check the GPS battery status as well as the connec-
tion to the pH data logger.
