Temperature Sensor
Select the type of temperature sensor used, Pt100 or Pt1000.
Temperature Coefficient
Notes.
• Displayed only if

• If is set to
A: Cond Units USP645
temperature coefficient is fixed automatically at 2.00%/C.
Enter the temperature coefficient ( x 100) of the solution (0.01 to 5.0%/C). If unknown,
the temperature coefficient () of the solution must be calculated – see Appendix A1.1.
If the value has not yet been calculated, set it to 2%/C provisionally.
TDS Factor
Note. Displayed only if
A: Cond.Units
The TDS factor must be programmed to suit the particular application – see Appendix A2.
Enter the required TDS factor between 0.4 and 0.8.
For salinity applications, set the TDS factor to 0.6.
TDS Units
Note. Displayed only if
A: Cond.Units
Select the TDS units (ppm, mg/l or mg/kg).
