8.3.4.7 Threshold value
Parameter: P29 Default value: 4 dB
Path: OPTIMIZATION / TRESHOLD VALUE
Description: Defining an upper limit value above the saved
background image described in 8.3.4.5 point.
The instrument will evaluate the measurement result as
a real echo when the reflected signal exceeds the saved
background level with the threshold value entered here.
Setting the threshold value is useful when the level in
the tank and the position of the (small surface) not-
moving disturbing object are the same. This case the
instrument will not regards the echo signal as false
reflection.
8.3.5 Calculations
8.3.5.1 Specific gravity
Parameter: P32 Default value: 0
Path: CALCULATION / SPECIFIC GRAVITY
Description: Entering a value (other than “0”) of specific gravity in this
parameter, the MASS value will be displayed instead of
Volume (VOL) in the dimension of tonne or lb/tonne
depending
on
P00 (c) and P02 (b).
8.3.5.2 Volume / Mass calculation mode
Parameter: P47: a Default value: 0
Path: CALCULATION / V/M CALC. MODE
Description: Calculation of the volume and mass can be performed
with two ways:

TANK FUNCTION/SHAPE – volume and mass
calculation with a tank shape formula. Entering
this menu point the table is automatically OFF.

V/M TABLE – volume and mass calculation with a
table.
Entering this menu point the table automatically
turns ON.
