Use this feature to offset the meter’s value
when cross referenced to another DO meter.
The Micro 600 DO allows +/- 10.0% offset
adjustment. View the offset value from the
Electrode Data menu “ELE.3”.
1 Using the % saturation mode of your
Micro 600 DO, observe the reading a
sample solution after it has stabilised.
2 Similarly, observe the reading of the
same sample using another DO meter as
a reference. The probe of the reference
meter should be immersed in the same
sample at the same depth.
3 Switch off the Micro 600 DO and enter
the % saturation setup menu.
4 Press ▲▼ to select “OFS.6”.

reading based on the last calibration before

reference DO meter.

Note: User calibrations will reset the
