The MSP400 leaves the factory with the bottom reference
20/4
4/20
ullage
liquid level
b.rEF
To change the bottom reference:
a)Press the green button ↓ to display the current “b.rEF” menu entry screen.
b)Press the blue button → to enter the “b.rEF” menu and to display the current bottom reference in use.
It is quite unlikely that the factory default value for bottom reference will suit your application. To edit the bottom reference, press the blue button → to enter the editing mode.
The leading digit of the current bottom reference will now be flashing, indicating it may be changed.
c)Use the green button ↓ to edit the value of the leading digit.
Be careful not to enter a value greater than the maximum range of the MSP400: 11m or 36ft.
The value of the leading digit should therefore be 1 or 3 as a maximum, depending upon the units of measurement chosen earlier.
Once correct, use the blue button → to select the next digit and then the green button ↓ to edit as before, or the blue button → to move to the next digit. Continue this sequence until all 5 digits are correct.
d)Press the blue button → a final time to confirm the new value. None of the digits should now be flashing.
e)If the new bottom reference value is incorrect, the edit sequence for the bottom reference can be re- started by pressing the blue button → again.
If the new bottom reference is correct, press the red button ↵ to save the new value to memory and automatically scroll on to the next main menu option:
Note:
If the user has chosen a duty of Flow or Contents, the next menu option offered will be “ProF”. Refer now to sections 4.4.4 to 4.4.9.
If the user has chosen a duty of Level or Distance, the next menu option offered will be “4”. Skip sections 4.4.4 to 4.4.9 and refer now to section 4.4.10.
TIP: a feature of the MSP400 useful at this stage is that it can be used as an electronic tape measure. With an empty tank or vessel, select Distance as the duty and the MSP400 will read the distance to the bottom of the tank. This can be noted and used when setting b.rEF
