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

23 to 25.
• If
A: Cond Units
the temperature coefficient is fixed automatically at 2.00%/ºC.
Enter the temperature coefficient (a x 100) of the solution (0.01 to 5.0%/ºC). If unknown,
the temperature coefficient (a) of the solution must be calculated - see appendix A.1.1
on page 74.
If the value has not yet been calculated, set it to 2%/ºC provisionally.
TDS Factor
Note. Displayed only if
The TDS factor must be programmed to suit the particular application - see appendix
A.2 on page 74.
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
Select the TDS units (ppm, mg/l or mg/kg).
Enable Calibration
