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. 4) 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 possibilities:
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 longitude
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
back on as a steady glow .
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 (p. 8).
