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 :
0
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.℃℉
6

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 :
0
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.
