key to return to the previous screen.
Auto:
The meter automatically chooses the range (ppm or ppt) to optimize
the measurement.
Auto ppt:
The meter automatically chooses the resolution to optimize the
measurement, readings will be in ppt only.
Specified numeric resolution: The meter will not autorange, the measurement will be displayed with
the selected resolution only.
7.3. PARAMETER COEFFICIENTS
EC Reference Temperature
Option: 20 °C or 25 °C
This value is used for temperature compensated conductivity. All EC measurements will be referenced
to the conductivity of a sample at this temperature.
Press the functional key to select the desired EC reference temperature.
EC Temperature Coefficient (Beta, ß)
Option: 0.00 to 6.00 %/°C
The temperature coefficient ß is defined by the following equation (using 25 °C as an example):
EC
25
=EC
x
/(1+ß(T
x
-25))
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.
