Setting Analog Output Conditions
To change the upper limit of scaling, set a new limit using
the parameter that follows.
Lower Limit of Scaling
screen
Lower limit of scaling setting
completed.
To return to the Analog Output Menu
screen, press .
Lower Limit of Scaling
Setting screen
Press once while
the setpoint is blinking.
The setpoint is confirmed and the PR300
returns to the Lower Limit of Scalling screen.
To return to the Measured Value
screen, hold down
.
If you do not operate any key for more
than 5 minutes on the Parameter
screen, the PR300 automatically
returns to the Measured Value screen.

NOTE
If the upper and lower limits of scaling do not satisfy the following conditional expression, the updated
upper or lower limit of scaling setpoint will not be incorporated but revert to the value before change.
