VI, Instructions:
1. Put the iron core connecting rod into the spool and lock the screw.
2. Cover the pressure tube with the iron core connecting rod and put the locking screw into the valve block.
3. The main part of the sensor is set on the pressure tube, and the zero screw is installed.
4, plug in the connection line and supply 24V to the sensor, make the sensor work normally, can be connected to the voltmeter or ammeter to monitor the output signal, turn zero screw, move the sensor internal coil on the position of the voltage tube, generally to half of the range as the starting point of the installation test, that is, the voltmeter, The ammeter output is 2.5V if it reads 0-5V, 5V if it reads 0-10V, and 12mA if it reads 4-20mA.
