4. MEASURING PROCEDURE

4-1 Conductivity measurement

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

( 3-2, Fig. 1 ) momentarily.

* Press the " Power Button " ( 3-2, Fig. 1 )

momentarily again will turn off the meter.

Connect the " Probe Plug " ( 3-13, Fig. 2 ) into the

" Probe input socket " ( 3-6, Fig. 1 ).

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

xx,x ℃uS

Now the meter is ready for the conductivity measurement.

2)Hold the " Probe Handle " ( 3-11, Fig. 2 ) by hand and

immerse the " Sensing Electrode " ( 3-12, Fig. 2 )

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

mS ( uS ) values, at the same time the left bottom

display will show the Temp. value of the measured

solution.

The method to change the Temp. unit from

" " to " " or " " to " ", please refer to :℃℉℉℃

Chapter 5-2 Change the Temp , unit, page 11.℃℉

When make the

measurement should

immerse the " Sensing

Electrode " immersed

wholly into the measured

solution.

4-2 TDS measurement

1)During the above 4-1 Conductivity measurement, if

press the " Hold button " ( 3-3, Fig. 1 ) continuously at

least two seconds will enter into the function of TDS

measurement with default, the display will show as :

xx,x ℃PPM

Other TDS measurement procedures are similar as Conductivity

measurement

2)During the TDS measurement, if press the " Hold

button " ( 3-3, Fig. 1 ) continuously at least two

seconds again will enter into the function of

Conductivity measurement with default, refer

section 4-1.

4-3 Data Hold

During the measurement, press the " Hold button " ( 3-3,

Fig. 1 ) once will hold the measured value & the LCD will

display a " HOLD " symbol.

* Press the " Hold button " once again will release the

data hold function.

4-4 Data Record ( Max., Min. reading )

* The data record function records the maximum and

minimum readings. Press the " REC button " ( 3-4, Fig. 1

) once to start the Data Record function and there

will be a " REC " symbol on the display.

* With the " REC " symbol on the display :

a)Press the " REC button " ( 3-4, Fig. 1 ) once, the

" REC MAX " symbol along with the maximum value

will appear on the display.

If intend to delete the maximum value, press the

" Hold button " ( 3-3, Fig. 1 ) once, the display will

show the " REC " symbol only & execute the

memory function continuously.

b)Press the " REC button " ( 3-4, Fig. 1 ) again, the

" REC MIN. " symbol along with the minimum value

will appear on the display.

If intend to delete the minimum value, press the

" Hold button " ( 3-3, Fig. 1 ) once, then the display

will show the " REC " symbol only & execute the

memory function continuously.

c)To exit the memory record function, just press the

" REC " button for 2 seconds at least. The display will

revert to the current reading.

4-5 Data Logger

The data logger function can save 1,600-point measuring

data.
