• Density adjustment changes the factory density calibration values or the calibration values set by
the service technician.
• The functions outlined in the following instructions are described in detail in the “Description of
Device Functions” manual.
1. Fill the sensor with fluid. Make sure that the measuring tubes are completely filled and that
liquids are free of gas bubbles.
2. Wait until the temperature difference between fluid and measuring tube has equalised. The
time you have to wait for equalisation depends on the fluid and the temperature level.
3. Using the local display, select the SETPOINT DENSITY function in the function matrix and
perform density adjustment as follows:
Function
No.
Function name Setting to be selected ( O or S )
(to next function with F )
6482 SETPOINT DENSITY Use P to select a 1- or 2-point adjustment.
!
Note!
When you press P you are automatically prompted to enter the access
code if the function matrix is still disabled. Enter the code.
6483 DENSITY SET VALUE 1 Use P to enter the target density of the first fluid and press F to save this
value (input range = actual density value ±10%).
6484 MEASURE FLUID 1 Use P to select START and press F .
The message “DENSITY MEASUREMENT RUNNING” appears on the
display for approximately 10 seconds.
During this time Promass measures the current density of the first fluid
(measured density value).
▼
For 2-point density adjustment only:
6485 DENSITY SET VALUE 2 Use P to enter the target density of the second fluid and press F to save
this value (input range = actual density value ±10%).
6486 MEASURE FLUID 2 Use P to select START and press F .
The message “DENSITY MEASUREMENT RUNNING” appears on the
display for approximately 10 seconds.
During this time Promass measures the current density of the second
fluid (measured density value).
▼
6487 DENSITY ADJUSTMENT Use P to select DENSITY ADJUSTMENT and press F .
Promass compares the measured density value and the target density
value and calculates the new density coefficient.
6488 RESTORE ORIGINAL If the density adjustment does not complete correctly, you can select the
RESTORE ORIGINAL function to reactivate the default density
coefficient.

Back to the HOME position:
→ Press and hold down Esc key (X) for longer than three seconds or
→ Repeatedly press and release Esc key (X) → Exit the function matrix step by step
