PARAMETER SETUP
EC Temperature Coefficient (Beta, ß)
Option: 0.00 to 6.00 %/°C
ß is a function of the solution being measured. For freshwater samples ß is approximately 1.90 %/°C.
If the actual temperature coefficient of the sample is known, press Modify to enter the value.
Press Accept to confirm the value or the ESC key to return to the previous screen.
TDS Factor
Option: 0.00 to 1.00
TDS is a calculated value based on the conductivity of the solution (TDS = factor x EC
25
). A typical
TDS factor for strong ionic solutions is 0.50, while for weak ionic solutions is 0.70 (e.g fertilizers).
Press Modify to enter the value.
Press Accept to confirm the value or the ESC key to return to the previous screen.
7.4. AVERAGING
Option: 1 to 20 samples
Averaging is a software filter to minimize sensor noise and provide more stable readings. It is
particularly useful to get a representative reading of the “average” value from flowing water.
Averaging will affect all measurements. If a fast response is needed, this value should be kept low.
Press Modify to select the number of samples to average.
Press Accept to confirm the value or the ESC key to return to the previous screen.
Note: When logging the first sample using averaging, it will be delayed by a few seconds.
