MEASURING and CALIBRATION
PROCEDURE
4-1 Dissolved Oxygen measurement
Fig. 2
1)Prepare the Oxygen Probe ( standard probe, DOPB-11 ),
install the " Probe Plug " ( 4-1, Fig. 2 ) into the
" DO Socket " ( 3-13, Fig. 1 ).
2)Power on the meter by pressing " Power Button "
( 3-2, Fig. 1 ) once.

Calibration at first
!
If it is the first time to use the Dissolved
Oxygen meter or after a certain period to
use the meter again, then it should to
execute the calibration procedures at the
first. For the measurement precisely
consideration, it recommend to make the
calibration before each measurement.
Calibration procedure, refer to chapter 4-2,
page 10.
4)a. Immersed the probe to a depth at least 10 cm of
the measured liquid in order for the probe to be
influenced by the temperature & automatic
temperature compensation to take place.
b. As for the thermal equilibrium to occur between the
probe & the measurement sample must be allowed
to pass, which usually amounts to a few minutes if
the Temp. difference between the two is only
several Celsius degrees.
5)a. In order to measure the dissolved oxygen content in
any given liquid, it is sufficient to immerse the tip of
the probe in the solution, making sure that velocity
of the liquid coming into contact with the probe is at
least 0.2 - 0.3 m/s or to shake the probe.
b. During laboratory measurements, the use of a
magnetic agitator to ensure a certain velocity in the
fluid is recommended. In this way, errors due to the
diffusion of the oxygen present in the air in the
solution are reduced to a minimum.

6)Display will show the Dissolved Oxygen values ( mg/L )
at the same time the bottom display will show the Temp.
value of the measured solution.
7)Rinsed the probe accurately with normal tap water after
each series of measurement.
Oxygen in the air
During the DO measurement, press the " Function Button "
( 3-6, Fig. 1 ) once, the display unit will show " %O2 "
instead of " mg/L " , it show the air Oxygen value for
reference.
@
Press the " Function Button " once again, the Display
unit will return to " mg/L ".
Change the Temp. unit to
л
If intend to change the Temp. unit from to ,кл
please refer to chapter 8-7, page 25.
"% Salt" compensation value adjustment
If intend to change the % Salt compensation value,
refer chapter 9-8, page 26.
"Height" compensation value adjustment
If intend to change the Height compensation value,
refer to chapter 8-9, 8-10, page 26 page 27.

4-2 Calibration
1)Install the " Probe Plug " ( 4-1, Fig. 2 ) into the
" DO Socket " ( 3-13, Fig. 1 ).
2)Power on the meter by pressing " Power Button "
( 3-2, Fig. 1 ) once.
Press the " Function Button " ( 3-6, Fig. 1 ) once, to
let Display unit will show " %O2 " instead of " mg/L ".
3)Wait for approx. 5 minutes at least until the
display reading values become stable & no
fluctuation.
4)Use the two fingers to press the " REC Button " ( 3-4,
Fig 1 ) and HOLD Button " ( 3-3, Fig. 1 ) at the same
time, the display will show the following screen as
example, release the both fingers.
20.9
CAL
5)Press the " Enter Button " , the Display value will count
from 30 to 0, then return to normal measuring screen
and finish the calibration procedures. The complete
calibration procedures will take 30 seconds
approximately.
Press the " Function Button " ( 3-6, Fig. 1 ) once,
to let Display unit to return " mg/L ".
Calibration Consideration :
a.As the oxygen in air is 20.9 % typically, so use
the environment air 02 value for quick &
precise calibration.
b
.
Please process calibration procedures under
wide and ventilating environment for best effect.

4-3 Probe maintenance
User first time to use the meter
Intend to let the DO probe keep the best
condition, when user receive the Oxygen Probe,
it should fill the Probe's Electrolyte at first.
User already use the probe for a certain
period :
Whenever user can not calibrate the meter
properly or the meter's reading value is not stable,
please check the oxygen probe to see if the
electrolyte in the probe head container is run out
or the diaphragm ( probe head with diaphragm
set) exist problem ( dirty ). If yes, please fill the
electrolyte or change the " Probe head with
diaphragm set " and make the new calibration.
The consideration of Diaphragm ( probe
head with diaphragm set
The oxygen probe component is the thin Teflon
diaphragm housed in the tip of the probe. The
diaphragm is permeable by the oxygen molecules but
not by the considerably larger molecules contained in
the electrolyte. Due to this characteristic, the oxygen
may diffuse throughout the electrolyte solution
contained in the probe, and its concentration may be
quantified by the measurement circuit.

Probe-filling Electrolyte,
OXEL-03
1)Unscrew the " Probe head " ( 5-3, Fig 3 ).
2)Pour out the old Electrolyte from the
container of the " Probe head ".
3)Fill the new Electrolyte ( OXEL-03 )
into the container of the " Probe
head " .
4)Screw the " Probe head " ( 5-3, Fig 3 )
into the probe body.
5)When not use the
probe, should insert Fig. 3
the " Probe head "
into the " Probe
protection cover " 5-1 Probe handle
