3.4.5 Damping Time Constant Setup
The damping time constant is set as specified in
the order when the instrument is shipped. Follow
the procedure below to change the damping
time constant. The damping time constant for the
amplifier assembly can be set here. The damping
time constant for the entire transmitter is the sum
of the values for the amplifier assembly and the
capsule assembly.
Any number from 0.00 to 100.00 can be set for the
damping time constant. Note that setting the quick
response parameter ON enables you to set the time
constant between 0.00 and 0.49 seconds.

3.4.6 Output Signal Low Cut Mode Setup
Low cut mode can be used to stabilize the output
signal near the zero point.
The low cut point can be set in a range from 0 to
20%, the direct ratio corresponding to the output
signal of 4 to 20 mA. (Hysteresis for the cut point:
±10% of the cut point)
Either
LINEAR or ZERO can be selected as the low
cut mode. Unless otherwise specified, the cut mode
is set to LINEAR at the factory.
Note that when the output modes of the output
signal and the display are selected as Sq root
and Linear accordingly, the low cut function is not
available for the display value.
