D
ISTANCE
(DIST) display
It is crucial to remember that the instrument is measuring distance as the base quantity, and all the other process values are calculated from this
base quantity.
The resolution of the measured distance is 1 cm, which is reflected in the calculated (level, volume) values. But the displayed value of the
calculated volume (VOL) can be rounded.

ISPLAY FORMAT The decimal position will be shifted as the displayed value increases (see table on
the left).
Values over one million will be displayed in exponential format, where the value (e)
represents the exponent. If the value exceeds 1x10
10
, the display will show Err4
(overflow).

TEPS OF ROUNDING
IN THE DISPLAYED VALUE
The mathematical operations will enlarge a couple of centimeters of fluctuation of
the base DIST value. This enlarged fluctuation in displaying VOL or FLOW can (if
disturbing) be avoided by rounding set in
P03 . The rounding value 2, 5, 10, etc.,
represents the steps by which the (one or two) last digit(s) of the calculated value
will be changed.
For example:
P03 =1 steps by 2: 1,000; 1,002; 1,004
P03 =5 steps by 50: 1,000; 1,050; 1,100 or
10,00; 10,05(0); 10,10(0); 10,15(0)
(the 0 of the steps 50, 100, 150, etc., will not be displayed)
