2.5.3 GAS EPS. R Dielectric constant (ε
r
) of the
gas in the tank. A major
parameter for TDR level
measurement devices. If the
dielectric constant of the gas
is very different from the
default value (air), set GAS EPS. GAS EPS. GAS EPS. GAS EPS.

2.5.5 PROD. EPS. R Dielectric constant (ε

the tank. If possible, type in the
exact value of the product's
dielectric constant. If you do not
know the exact value, use 2.5.2

2.5.6 MEAS. AMP. Measured pulse amplitude.
This is the amplitude of the
signal (after reflection on the
surface of the tank contents)
compared with the amplitude of
the reference pulse. This value
is measured in thousandths
(1...1000) of the reference pulse
amplitude (value= 1000).
Although this data refers to any
point along the device
measuring range, the value
shows the attenuation of the
signal amplitude at a distance
of 1 m / 3.3 ft from the thread
stop. This value helps you to set
the measurement threshold in
menu item 2.5.7 MEAS.
THRESH.
2.5.7 MEAS. THRESH. Measurement threshold. If it is
difficult to identify the level
signal (for example: too many
parasite signals), you can
increase the threshold. This
value is measured in
thousandths (1...1000). A
threshold of 100 is equivalent to
10% of the amplitude of the
reference pulse at a distance of
1 m / 3.3 ft from the thread
stop. For more data, refer to
Thresholds and parasitic
signals on page 51.
