• Follow LCD calibration indication. Adjust the calibration knob
until the display shows “ 12.88 mS” i.e. the conductivity reading
@ 25°C.
• All subsequent measurements will be compensated to 25°C (77°F).
If you prefer to standardize the temperature compensation to
20°C (68°F) rather than 25°C (77°F), adjust the knob to read
“
11.67 mS” (see the conductivity vs. temperature chart on page 13).
All subsequent measurements will be compensated to 20°C.
• The calibration is now complete and the instrument is ready for
use.
The instrument should be recalibrated at least once a month, or
when the probe is changed.
Note: For more accurate results, it is advisable to use a calibration
solution close to the range to be measured. See the “Accessories”
section for a wide selection of conductivity solutions.
