Tip: If you have your GPS unit set properly and
have checked the connection but still are not get-
ting geo-referenced data, uncheck the box requir-
ing the digital correction in Meter Settings (pp.
8 -
9
) .
Initial GPS connect
If the meter does NOT detect an incoming GPS signal,
it will flash steadily for 10 seconds and then glow
steadily once it gets into
Measurement
mode. If it
does detect the GPS signal (satellites found etc..), it
gives a series of 3 rapid flashes before going to the
steady glow for
Measurement
mode. If a GPS signal
is not found during power-up, the meter will not search
for it when taking readings and no geo-referenced data
will be collected during that sampling session. 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. 7) before taking any readings.
Taking measurements
If the meter did NOT detect the GPS initially, once in
Measurement
mode, the LED will go off and on very
quickly when a measurement is taken.
If it did detect the GPS signal initially, once in
Meas-
urement
mode, it will look for the GPS signal at the
time of every measurement. There are two possibili-
ties:
1. If it sees the GPS signal at the time of measurement,
the LED will go off for a noticeably longer time and then
come back on as a steady glow. Latitude and longi-
tude values will be added to the data file. The meter is
again ready to take a reading when the LED returns to
a steady glow.
2. If it does NOT see the GPS signal at the time of
measurement (signal lost, batteries die, cable gets
pulled out), the LED will flash briefly and then come
