23.1. Measurement with automatic temperature compensation
In order to make measurement with automatic temperature compensation:
- connect the oxygen sensor and the temperature probe to the O2 and t
connectors respectively (Pic. 2), the symbol will appear;
- immerse the oxygen sensor and the temperature probe in the measured
solution;
- switch the meter on with the button;
- choose the measuring function with the
button;
- choose the unit according to the section 21.1;
- in case of accurate measurements in mg/l enter the salinity value
(section 21.2);
- check or simulate flow of the measured solution;
- wait about 1 min until the reading stabilises and check it.
23.2. Measurement with manual temperature compensation
In order to make measurement with manual temperature compensation:
- disconnect the temperature probe;
- switch the meter on with the button;
- choose the measuring function with the
button;
- choose the unit according to the section 21.1;
- in case of accurate measurements in mg/l enter the salinity value
(section 21.2);
- immerse the oxygen sensor in the measured solution;
- measure the temperature of the solution with a laboratory thermometer;
- with the ,
buttons enter the temperature value of the measured
solution into the lower row of the LCD (pressing of both , buttons
simultaneously sets the temperature to 20
o
C);
- check or simulate flow of the measured solution;
- check the reading when it stabilises.
In case of measurement series it is possible to adjust the temperature
compensation each time the temperature of the solution changes.
Uwaga: in case of measurements in solutions with low salinity, check
according to the section 21.2 if the introduced salinity value is
equal 0.00 g/l.
