3.1 Display current value A/D-converter 1 (Density)
3.2 Display Voltage level A/D-converter 2 (Velocity)
3.3 Selection Current value for test purposes.
Here a constant current ( 4, 8, 12, 20mA)
can be presetted on output 1 for testing purposes.
Here a constant current ( 4, 8, 12, 20mA)
can be presetted on output 2 for testing purposes.
3.4 Entry of the minimum value for the density range.
usually 0-value (Measuring pipe empty).
The dimensionless value must be changed
so far, until 0% are indicated.
3.5 Entry of the maximum value for the density range.
Here you can enter the value, which can
maximally be expected or a second measuring
point. The dimensionless value must be changed
so far, until the requested percentage is indicated.
