! Note!
The option is only active if the OFF, °BRIX or FLEXIBLE option was not
selected in the "Dens. - Function" parameter ( → Page 160).
Use this parameter to enter the reference temperature for the density
functions.

Dens.- -Mode AUTO - OOS
! Note!
The option is not active unless FLEXIBLE was selected in the parameter
"Dens. - Function" ( → Page 160).
Use this parameter to select a user-specific method of calculating the
concentration of the density and temperature measured.
In order to use this function, the following values are required:
• Concentration (see formula)
• Currently measured density
• Currently measured temperature
The concentration is calculated from the density and temperature as follows:
K = A0 + A1 · ρ + A2 · ρ
2
+ A3 · ρ
3
+ A4 · ρ
4
+ B1 · T + B2 · T
2
+ B3 · T
3
K = Concentration
ρ = Currently measured density
A0 = Value from Dens. - A0 parameter
A1 = Value from Dens. - A1 parameter
A2 = Value from Dens. - A2 parameter
A3 = Value from Dens. - A3 parameter
A4 = Value from Dens. - A4 parameter
B1 = Value from Dens. - B1 parameter
B2 = Value from Dens. - B2 parameter
B3 = Value from Dens. - B3 parameter
T = Currently measured temperature in °C
Options:

! Note!
The relationship between the individual values (concentration, density and
temperature) can also be determined via the ToF Tool-Fieldtool Package
operating program and be transmitted to the measuring device.
