COND.
TEMP.
• Press COND/TEMP again to display conductivity
measurement.
• Select 19.99 mS/cm range by pressing the
appropriate range key.
• Adjust the calibration trimmer (see page 5, #6) on the side of
the instrument with the calibration screwdriver until the display
shows the conductivity reading at 25°C (see the conductivity vs.
temperature on page 18). E.g. @ 25°C, 12880 µS/cm =
12.88 mS/cm.
• 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), leave the TEMPERATURE
knob at 18°C (if the temperature of the solution is 18°C), adjust
the trimmer to read "11.67 mS" (see the conductivity vs. tem-
perature chart on page 18). 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 re-calibrated at least once a month, or
when the probe or battery is changed.
Note: For more accurate results, it is advisable to use a calibration
solution close to the measurement range . See the accessories
section on page 23 for a wide selection of conductivity solu-
tions.
