Fluoride calibration
The fluoride measurement is calibrated at 2 points, which should
be as far from each other as possible, but within the measurement
range. The lower value must be calibrated with a lower fluoride
concentration than the upper value, e.g. lower value 0.20 mg/l and
upper value 2.00 mg/l.
Calibration solutions for 0.20 mg/l, 2.00 mg/l and 100 mg/l are
available.
Please note
Before use, the electrode must be placed in a 100 mg/l fluoride
solution at pH 7 for approx. 24 hours. This is necessary to
guarantee that the electrode functions properly.
1
Starting from the basic display in the main menu, select the
"Calibration" menu.
2
Select the menu item “Fluoride (1) ... (4)“ for the measurement
you wish to perform.
3
Fill 10–20 ml of the lower concentrated standard solution in
one of the supplied beakers and place in the bottom clip. Dip
the electrode at least 2 cm.
4
Select "Cal. lower value" in the menu and press "Enter".
5
Enter the calibration solution value using the arrow keys and
wait until the measured value on the display remains constant.
6
Save the value by pressing "Enter".
7
Select "Cal. upper value" in the menu and press "Enter".
8
Wash electrode with distilled water and fill 10–20 ml of the
higher concentrated standard solution into one of the supplied
beakers. Dip electrode.
9
Enter the calibration solution value using the arrow keys and
wait until the measured value on the display remains constant.
10
Save the value by pressing "Enter".
11
Place the sensor in the flow-through adapter again.
This concludes the fluoride calibration.
