5. CONDUCTIVITY/TDS MEASURING
and CALIBRATION PROCEDURE
The meter default function are following :
* 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 disable.
* The sampling time of data logger function is
2 seconds.

5-1 Conductivity measurement
1) Prepare the Conductivity Probe ( CDPB-04, standard
accessory, included ), install the " Probe Plug " ( 3-20,
Fig. 1) into the " Probe Socket " ( 3-13, Fig. 1 ).
2) Power on the meter by pressing and holding " Power Button "
( 3-2, Fig. 1 ) for at least 1.5 seconds .
Select the Meter's measurement FUNCTION to " CD "
( Conductivity measurement ), refer to chapter 4, page 7 .
3) Hold the " Probe Handle " ( 3-18, Fig. 1 ) by hand
and let the " Sensing head " ( 3-19, Fig. 1 )
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.
Manual range operation
The meter is default to be used for the auto range
mode. by pressing and holding the " Range Button " ( 3-5, Fig. 1 )
continuously in sequence will change the range from 20uS ,
200 uS, 2 mS , 20 mS, 200 mS and auto range.
