0 – 10V DC is output in proportion to 0 – 100% output set-

points. Insert a tester with a diameter of 2.0 mm (.08”) into

the monitor jack to check the output value. For example, in

order to output 12mA with output 4 – 20mA DC, adjust the

setpoint so that the monitor output becomes 5V.

• Setpoint adjustment

Adjust the setpoint while checking the monitor output.
