Material
Selects the appropriate echo processing algorithms for the material [see
Position Detect
(2.8.4.2.)
for more detail].
Options
*
LIQUID
LIQUID LOW DK
a)
(low dielectric liquid – CLEF algorithm enabled)
a)
dK < 3.0
Response Rate
Sets the reaction speed of the device to measurement changes in the target range. Use a
setting just faster than the maximum filling or emptying rate (whichever is greater).
Options
Response Rate (1.3.)
Fill rate per Minute (2.4.2.)/Empty rate per
Minute (2.4.3.)
*
SLOW
0.1 m/min (0.32 ft/min)
MED
1.0 m/min (3.28 ft/min)
FAST
10.0 m/min (32.8 ft/min)
