P800 Near Blanking
Sets the amount of blanking as measured from the flange face and extending into the
measurement range. See Blanking on page 46.
Range: 0 to 9999
Values
Pre-set: 0.4m
Enter value in units of P005.

: This parameter may be set at the factory. If so, the appropriate values appear
on the product tag.
P801 Range Extension
Sets the amount of range extension as measured from the empty distance (P006) and
extending into the far-end blanking. See Blanking on page 46.
Range: 0 to 99%
Values
Pre-set: 5%
Enter value as a % of P006. The distance below empty is not blanked.

empty tank reads empty.
