It is important to note that the increase in concentration of salts dissolved in solution 
increases the conductivity of that solution. This relationship varies from salt to salt 
and is roughly linear over a given range for a given salt. The TDS conversion factor is 
the number used by the meter to convert from conductivity to TDS.  
Instead of calibrating for TDS directly using TDS calibration standard solutions, you 
can have TDS calibration by using the conductivity calibration method and enter the 
appropriate TDS conversion factor into the meter.  
For more information regarding TDS Conversion Factor determination, please refer to 
page 73.  

 

The factory default setting for TDS conversion factor is 0.5. 
If your solution has a different TDS factor, you can improve 
calibration accuracy by setting the TDS factor prior to 
calibration. 

1.  Press MODE key to select TDS mode. 
2.  Press Setup key to enter SETUP Menu. 
3. Press 

the 

HOLD/ENTER 

key a few times to scroll 

through the sub programs until you view Program 
P1.4 

4.  Press the HOLD/ENTER key again. The upper 

display shows a value and the lower display shows 
“tdS”. 

5.  Press the MI/▲ or MR/▼ keys to select your 

calculated TDS conversion factor. 

6.  Press the HOLD/ENTER key to confirm selection 

and to return to the subgroup menu. 

7. Press the CAL/MEAS key to return to 

measurement mode.  

NOTE: The set up program P1.4 for setting the TDS 
conversion factor is only activated when set up menu is 
entered while the meter is in the TDS measurement mode.
