8.5.5.1.2 1-Point Calibration of the
Fluoride Sensor
Calibration of fluoride. Description of 1-
point calibration
One container with a calibrating solution is
required for calibration.
1.
Select Calibration menu
ð
In "Temperature Correction
Value manual" operating mode,
the calibration display appears
and the temperature value
flashes.
In "Temperature Correction
Value automatic" operating
mode the calibration display
appears
2. Measure the temperature of the cal‐
ibrating solution 1 using the ther‐
mometer (only in "Temperature
Correction Value manual" operating
mode)
3. Enter the determined value for the
calibration solution temperature
using the keys , and into
the DULCOMETER

D1Cb / D1Cc
allows for the
actual temperature of the cali‐
bration solution during the cali‐
bration.
5. Immerse the fluoride sensor in cali‐
brating solution 1 and wait until the
mV value displayed remains steady
(fluctuation of < 0.05 mV/min)
