As long as the acquisition software is closed properly using F12, all data is saved and

the acquisition can be opened at a later time with new data being appended to the data

taken previously.

Ref check light This

green light indicates a

good reference

These indicate the temperatures and the

humidity of the system. If they are not

within range (see specifications) the

indicator light will be red, if this occurs

the system should be shut down.

Dark spectrum

mode.

Ref check

compares the

reference data

to current

reference.

As in system check, this should be close to a straight line

except for the edges and the center. Since this is a bad

reference it is indicated by the ref check light at the top of the

screen. In this situation press F2 to store a new reference.

Pressing

PROBE stores

spectrum data

as absorbance

and auxiliary

data, which

includes EC

data, until

probe has

been hit again

or logging

stops

automatically

when probe

pulled out of

ground. No

data can be

logged if there

is no GPS

signal or there

is a bad ref

check. Use

PROBE to

store data

while mapping

a field. No

data, including

EC data, will

be stored

unless it

program is in

LOG mode.

Auxiliary data indicator

Auxiliary data can

be scrolled

through by

pressing the up or

down arrow to the
