Commissioning Cubemass DCI MODBUS RS485
62 Endress+Hauser
• Density adjustment changes the density calibration values set at the factory or by the service
technician.
• The functions outlined in the following instructions are described in detail in the "Description of
Device Parameters" manual.
1. Fill the sensor with fluid. Make sure that the measuring tubes are completely filled and that
the fluid is free from gas bubbles.
2. Wait until the temperature difference between the fluid and measuring tube has equalized.
The time you have to wait for equalization depends on the fluid and the current 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 whether 1- or 2-point density adjustment is to be
performed.
!
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 VAL 1 Use P to enter the target density of the first fluid and press F to save
this value (input range = current 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 Cubemass DCI measures the current density of the first
fluid (actual density value).
Æ
For 2-point density adjustment only:
6485 DENSITY SET VAL 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 Cubemass DCI measures the current density of the
second fluid (actual density value).
Æ
6487 DENSITY ADJUST Use P to select DENSITY ADJUST and press F.
The measuring device compares the current density value and the target
density value and calculates the new density coefficients.
6488 RESTORE ORIGINAL If density adjustment does not run correctly, you can select the
RESTORE ORIGINAL function to reactivate the default density
coefficients.
Æ
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
