Change the Temp. Coefficient Factor
The default Temp. compensation factor value of the
measurement solution is to 2.0% per . If intend to
℃
change it, please refer to chapter 12-11, page 45.
Zero adjustment
If the probe not immerse the measurement solution and
display not show zero value, pressing the " Zero Button "
( 3-5, Fig. 1 ) continuously at least 10 seconds will let
display show zero. The zero function only valid for the
200 uS range and the not zero value is < 2.0 uS.
6-2 TDS ( PPM ) measurement
The measuring procedures are same as above
6-1 Conductivity ( uS, mS ) measurement,
except to change the display unit from uS, mS to PPM.
The detail procedures please refer chapter 12-12, page 45.
6-3 Calibration
1)Prepare the standard conductivity solution ( optional )
For example :
2 mS range calibration solution :
1.413 mS Conductivity Standard Solution, CD-14
200 uS range calibration solution :
80 uS Conductivity Standard Solution
20 mS range calibration solution :
12.88 mS Conductivity Standard Solution
or other Conductivity Standard Solution
