䢇 [NO/NC], [Display cycle], [Response time] and [Pressure range] can be
set by the following procedure.
Hysteresis mode
䢇 The hysteresis of the comparative outputs can be set arbitrarily by the set
values for ON/OFF control.
Window comparator mode
䢇 The comparative output can be turned ON or OFF by a pressure which is
within the set pressure range.
Forced output mode
䢇 The comparative output is forcibly maintained at OFF level in the sensing
mode, irrespective of the set values. Hence, it is convenient for only display-
ing the pressure value without using the comparative outputs.
Further, since the comparative outputs can be forcibly switched ON or OFF
with key operation, without actually applying pressure, this mode is suitable
for an operation check or a start-up check.
<Operation example>
䢇 The displayed pressure when the pressure port is left open is adjusted
to zero.
䢇 [Display mode], [Output mode] and [Unit] are set by the following pro-
cedure.
q In the sensing mode, press both UP key and MODE
key, simultaneously, to change the mode to the initial
setting mode.
w The settable digit blinks.
e Setting item changes when UP key is pressed.
r Setting condition of each item changes when DOWN
key is pressed.
q In the sensing mode, press both DOWN key and MODE
key simultaneously to change to the supplementary set-
ting mode.
w The setting item and the setting condition are displayed
alternately.
e The setting item changes when UP key is pressed.
r The set condition of each item changes when DOWN
key is pressed.

and then,
when the keys are released, the zero-point adjustment
is completed and the sensor returns to the sensing
mode.
Automatic sensitivity setting mode
䢇 After [Set Value 1 (P-1)] and [Set Value 2 (P-2)] of the comparative output are
set, [Set Value 3 (P-3)] is automatically set.
