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).

 

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 .
