(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 correspond-
ing 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 specified, 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.
• Example: Change the low cut setting range
from 10% to 20%, and the low
cut mode from
LINEAR to ZERO in
the SQUARE ROOT output mode.
