malfunction may result due to noise.
Ensure that the FG terminal is connected to ground when using a commercially available switch-mode
power supply. When a switch-mode power supply is connected to the product, switching noise will be
superimposed and the product specification can no longer be met. This can be prevented by inserting a
noise filter, such as a line noise filter and ferrite core, between the switch-mode power supply and the
product, or by using a series power supply instead of a switch-mode power supply.
○Connector
Connecting/Disconnecting
When mounting the connector, insert it straight into the socket, holding the lever and connector body, and
push the connector until the lever hooks into the housing, and locks.
When removing the connector, press down the lever to release the hook from the housing and pull the
connector straight out.

Pressure Setting
■Measurement mode
The measurement mode is the condition where the pressure is detected and displayed, and the switch
function is operating.
This is the basic mode, and other modes should be selected for setting changes and other function settings.
Setting the ON and OFF points of the Pressure switch.
Operation
When the pressure exceeds a set point, the Pressure switch will be turned ON.
When the pressure falls below the set point by the amount of hysteresis or more, the Pressure switch will be
turned OFF.
The default setting of the output set value is the central value between the atmospheric pressure and the
upper limit of the rated pressure range.
If this condition, shown below, is acceptable, then keep these settings.
