(3) Damping Time Constant Setup
(C30: AMP DAMPING)
When the instrument is shipped, the damping time
constant is set at 2.00 seconds unless otherwise
speciedintheorder.Followtheprocedurebelow
to change the damping time constant.
Note that setting the quick response parameter
(D50: QUICK RESP) ON enables you to set the
damping time constant between 0.00 to 0.49
second.
• Example: Change from 2.00 to 4.00 seconds.

Note 1: The damping time constant set here is the time
constantfortheamplierassembly.Thedampingtime
constant for the entire transmitter is the sum of the
valuesfortheamplierassemblyandforthecapsule
assembly.
Note 2: When the damping time constant is set to less than
0.5 second, communication may occasionally be
unavailble during the operation, especially while output
changes dynamically.
(4) Output Mode and Integral Indicator
Display Mode Setup
(C40: OUTPUT MODE, I20: P DISP
MODE)
The mode setting for the output signal and the
integral indicator can be performed independently.
Thismodeissetasspeciedintheorderwhenthe
instrument is shipped. Follow the procedure below
to change the mode.
If the instrument is equipped with an integral
indicator and the display mode is SQUARE ROOT,
“ ” is displayed on the integral indicator.
• Output mode for 4-20 mA output
• Example: Set output mode from Linear to
Square root.

(5) Output Signal Low Cut Mode Setup
(D10: LOW CUT, D11: LOW CUT MODE)
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: ±10% of the cut point)
Either LINEAR or ZERO can be selected as the low
cutmode.Unlessotherwisespecied,thecutmode
is set to LINEAR at the factory.
Note that when the output modes of the output
signal and the integral indicator are selected as
SQUARE ROOT and LINEAR accordingly, the low
cut function is not available for the integral indicator
display.
