4. MEASURING PROCEDURE

4-1 Check the water's conductivity (water condition)

1)Turn on the meter by pressing the " Power Button "

( 3-3, Fig. 1 ) momentarily.

* Press the " Power Button " ( 3-3, Fig. 1 )

momentarily again will turn off the meter.

The " Display " ( 3-2, Fig. 1 ) will show the unit as :

uS 0

Now the meter is ready for the measurement.

2)Hold the meter by hand and immerse the " Sensing

Electrode " ( 3-6, Fig. 1 ) immersed wholly into the

measured solution. Shake the " Sensing Electrode " to

let the electrode's internal air bubble drift out from the

sensing Electrode.

" Display " ( 3-2, Fig. 1 ) will show the conductivity

values in uS unit,

When make the

measurement should

immerse the " Sensing

Electrode " immersed

Fig. 2 wholly into the measured

solution.
