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.
