9.1.1.
Setpoint
Setpoint function outputs a signal indicating if the measured pressure is below a
certain pressure value. The signal is outputted in the open collector form (Lo output
when setpoint is ON).
The rating of the is [24 VMAX, 50 mAMAX, saturation voltage is 1V].
9.1.2.
Setting of setpoint
The setpoint value is set with a trimmer on the SP1 front panel. (See section 8)
Values that can be set are 1.0

measurement range.
9.1.3.
Setpoints of measuring unit and display unit
The setpoint of the display unit and that of the measuring unit (sensor unit, box unit)
are independent of each other. Therefore, both will be effective if setpoints are taken
out separately from the display unit and measuring unit.
However, only the value set by the display unit will be effective if the setpoint point of
the display unit and that of the measuring unit are connected and only the setpoint
from the display unit are taken out.
