Taking Measurements

1. Connect the Conductivity Electrode (Figure 1, 12) to the Electrode. Input Socket (Figure 1, 7).
2. Power on the instrument by pressing the Power ON Button.
3. Select the 2 mS/cm or 20 mS/cm range by pressing the appropriate range button (Figure
1, 5 or 6).
4. Holding the electrode handle (Figure 1, 11), immerse the conductivity electrode completely in
the sample. Shake the electrode several times to remove air bubbles from the electrode and
therefore ensure stable readings. The instrument will display the conductivity value in mS/cm.
Note: „1" in the display indicates an out-of-range measurement. When operating in the 20
mS/cm range, if the value obtained has one or more zeros after the decimal point, change to
the 2 mS/cm range for improved accuracy.

5. Calibration

To calibrate the meter:
1. Prepare a 1.413 mS/cm calibration solution (Order Code 722250) or similar.
2. Select the 2 mS/cm range (Figure 1, 5).
3. Holding the conductivity electrode by its handle (Figure 1, 11), immerse it completely in
the calibration solution. Shake the electrode to disperse air bubbles on it and allow meas-
urements to stabilise. Adjust „Calibration Adjust LR" (see above) until the display reads
exactly 1.413 mS/cm.

Changing the Battery

1. „ " in the left corner of the display indicates that it is necessary to replace the battery.
