Lutron Electronics CD-4318SD - TDS ( PPM ) Measurement; Calibration

Change the Temp. unit to
℉
℉℉
℉
If intend to change the Temp. unit from ℃ to ℉, please
refer to chapter 10-7 page 23.
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 10-8, page 24 .
Zero adjustment
If the probe not immerse the measurement solution and
display not show zero value, pressing the " HOLD Button "
( 3-3, Fig. 1 ) continuously at least 10 seconds will let
display show zero. The zero function only valid for the
20 uS range and the not zero value is < 2.0 uS.
5-2 TDS ( PPM ) measurement
The measuring procedures are same as above
5-1 Conductivity ( uS, mS ) measurement,
except to change the display unit from uS, mS to PPM.
The detail procedures please refer chapter 4, page 7 .
5-3 Calibration
conductivity 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
2) Install the " Probe Plug " ( 3-20, Fig. 1 ) into the
" CD Socket " ( 3-13, Fig. 1 ).
