* One meter for multi purpose operation :
Conductivity, TDS ( Total dissolved solids ), Salt measurement.
Conductivity : 200 uS/2 mS/20 mS/200 mS.
*
* Salt : 0 to 12 % salt ( % weight ).
onductivity measurement can select Temp. Coefficient
* C
of measurement solution.
ATC for the conductivity measurement.
*
* Separate probe, easy for operation of different
measurement environment.
* Real time SD memory card Datalogger, built-in Clock
and Calendar, sampling time can set from 1 sec to 8
hour 59 min. 59 sec.

a. Conductivity, TDS measurement
b.TDS measurement
c. Salt measurement
Pressing the " Mode Button " ( 3-5, Fig. 1 ) once, the
Display will show the following text in sequence :
Cd Conductivity measurement
tdS 'TDS measurement
SALt Salt measurement
Until the Display show the desired mode the meter will
execute this Mode with default.
5. CONDUCTIVITY/TDS MEASURING

*The display unit is set to conductivity ( uS, mS ).
*
The temperature unit is set to .℃
*
Temp. compensation factor is set to 2.0% per C.
Auto range.
*
*
Auto power off.

5-1 Conductivity measurement
1)Prepare the Conductivity Probe ( CDPB-03, standard
accessory, included ), install the " Probe Plug " ( 5-1,
Fig. 2 ) into the " Probe Socket " ( 3-13, Fig. 1 ).
2)Power on the meter by pressing " Power Button "
( 3-2, Fig. 1 ) once.
Select the Meter's measurement Mode to " Cd "
( Conductivity measurement ), refer to chapter 4, page 8.
3)Hold the " Probe Handle " ( 5-2, Fig. 2 ) by hand
and let the " Sensing head " ( 5-3, Fig. 2 )
immersed wholly into the measured solution. Shake
the probe to let the probe's internal air bubble drift
out from the sensing head.
Display will show the conductivity mS ( uS ) values.
at the same time the left bottom display will show the
Temp. value of the measured solution.
