4. 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:
i) Prepare a 1.413 mS/cm calibration solution (Order Code 722250) or similar.
ii) Select the 2 mS/cm range (Figure 1, 5).
iii) 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 measurements to stabilise. Adjust „Calibration Adjust LR“ (see
above) until the display reads exactly 1.413 mS/cm.

6. CHANGING THE BATTERY
i) „ “ in the left corner of the display indicates that it is necessary to replace
the battery. However, accurate measurements may still be made for several
hours after the “Low Battery” indicator first appears.
ii) Remove the protective cover before replacing the battery. To replace the battery,
remove the Battery Compartment Cover (Figure 1, 9) on the rear of the meter.
iii)Remove the battery, install a replacement one (006P DC 9V battery
(heavy duty type), MN1604 (PP3) or equivalent) and replace the battery
compartment cover.
7. ACCESSORIES
