5) • Remove the protective cover from the probe head and
immerse the probe to a depth of at least 10 cm in the meas-
ured liquid in order for the automatic temperature compensa-
tion to take effect.
• Thermal equilibrium must occur between the probe & the
measurement sample, which usually takes to a few minutes
if the Temp. difference between the two is only a few degrees
Celsius.
• 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 the velocity of the liquid coming
into contact with the probe is at least 0.2 - 0.3 m/s. This is
achieved by swirling the probe in the solution.
• During laboratory measurements, the use of a magnetic
stirrer/ agitator is recommended. In this way, errors due to air
diffusion in the solution are reduced to a minimum.
6) The display will show the Dissolved Oxygen values (mg/L). At the
same time, the bottom left display will show the Temp. value of
the measured solution.
7) Rinse the probe carefully with normal tap water after each
series of measurements.
Oxygen in the air
When the display unit shows “%O
2
“, this represents an approxi-
mate air Oxygen value.
Changing the Temp. unit to °F
To change the Temp. unit from °C to °F, please refer to page 28,
chapter 7.6 (Temp. Unit Default Setting).
“% Salt“ compensation value adjustment
To change the % Salt compensation value, refer to page 29, chap-
