OPERATING MANUAL TMU-W / UMC4
7.2.6.3
Factor programmable density unit
To display another density unity than one of the predefined standard units a factor can be entered for the
conversion of the reading.
F = 0998.0 g/l
The factor always refers to the unity of g/l.
The Factor value for density will be displayed and can be changed by toggling the arrow keys.
Pressing the “Enter” key confirms the entry.
7.2.6.4
Density lower-range value
This function allows the operator to define the lower-range value for density measurement in the selected unit.
If density is equal or below this value, the assigned current output will be set to its initial value of 0/4 mA.
After selecting the Density lower-range value function, press “Enter” to display the following selection field:
Density 0 % =
XXXXX g/l
The current lower-range value will be displayed and can be changed by toggling the arrow keys.
Confirm the entry with “Enter”.
7.2.6.5
Density upper-range value
This function allows the operator to define the upper-range value for density measurement in the selected unit.
For this density, the assigned current output will be set 20 mA. The applied current of the current output
assigned to the density value is linearly interpolated based on the ratio between the measured value and the
difference between lower- and upper-range value.
After selecting the Density upper-range value function, press “Enter” to display the following selection field:
Density 100 % =
XXXXX g/l
The current upper-range value will be displayed and can be changed by toggling the arrow keys.
Pressing the “Enter” key confirms the entry.
