Measurement

 

and

 

Display

 

Considerations

 

The

 

DO600

 

uses

 

a

 

polarographic

 

sensor,

 

which

 

consumes

 

oxygen

 

at

 

the

 

sensing

 

surface.

This

 

requires

 

a

 

constant

 

movement

 

of

 

the

 

sample

 

across

 

the

 

membrane

 

to

 

maintain

 

a

constant

 

dissolved

 

oxygen

 

level.

 

It

 

is

 

recommended

 

that

 

the

 

probe

 

be

 

moved

 

in

 

the

 

sample

as

 

the

 

measurement

 

is

 

made,

 

or

 

if

 

in

 

a

 

laboratory

 

environment,

 

the

 

sample

 

be

 

stirred

 

using

a

 

stir

 

plate.

If

 

you

 

are

 

measuring

 

DO

 

in

 

a

 

small

 

container,

 

the

 

probe

 

will

 

consume

 

oxygen

 

as

 

it

 

is

measuring

 

and

 

the

 

measurement

 

value

 

will

 

continue

 

to

 

go

 

lower.

 

If

 

the

 

unit

 

appears

 

to

 

be

 

locked

 

(display

 

frozen).

 

It

 

is

 

possible

 

that

 

the

 

Data

 

Hold

 

mode

 

has

been

 

inadvertently

 

accessed

 

by

 

a

 

press

 

of

 

the

 

MODE/HOLD

 

button

 

(HOLD

 

will

 

be

 

displayed

in

 

the

 

bottom

 

left

 

of

 

the

 

LCD).

  

Simply

 

press

 

the

 

MODE/HOLD

 

button

 

again

 

or

 

turn

 

the

meter

 

off

 

and

 

back

 

on

 

again.

 

If

 

the

 

meter

 

does

 

latch

 

up

 

and

 

no

 

button

 

presses

 

revive

 

it,

 

remove

 

the

 

batteries

 

and

 

restart.

For

 

maximum

 

accuracy,

 

allow

 

sufficient

 

time

 

for

 

the

 

temperature

 

of

 

the

 

probe

 

to

 

reach

 

the

temperature

 

of

 

the

 

sample

 

before

 

taking

 

a

 

reading.

 

This

 

will

 

be

 

indicated

 

by

 

a

 

stable

temperature

 

reading

 

on

 

the

 

display.
