 DO mg/L (ppm) Concentration measurement 
is dependent on the temperature of the 
sample to be measured. Most users will 
choose to have the DO6 automatically 
compensate for temperature using the 
temperature sensor that is built into the DO 
probe. However, it is possible to manually 
enter a known temperature to the meter 
(manual temperature compensation). The 
built-in temperature sensor of the DO6 probe 
is factory calibrated. However, the 
temperature can be re-calibrated if needed 
and is recommended when a replacement 
probe is used.  

Before calibration, ensure that the meter 
displays annunciator “A” to indicate that it is 
in automatic temperature compensation 
mode. Please see Set Up menu on page 36 
for its activation procedure.  

1)  Switch the meter on. Press MODE to 

select temperature mode. The display 
should show the annunciator “T” for 
temperature mode and “A” for automatic 
temperature compensation mode. 

2)  Dip the probe to a solution of known 

temperature (i.e. a temperature 
bath).Allow some time for the reading to 
stabilize. 

3)  Press the CAL key. The CAL indicator 

will appear and blinks above the display. 
The temperature value displayed is with 
respect to the factory default calibration.
