Do not move the potentiometer “R†, intelligent transmitter If you need to adjust, you need to have the following two conditions: 1. The range needs to be changed. After consultation with the manufacturer, it is determined to be within the adjustment range. 2. The site has the required equipment and is operated by professional technicians.  Eight, wiring method  For the connection of various specific instruments, the pressure transmitter output model and electrical connection are as follows: Two-wire 24VDC power supply, 4--20mA output Three (four) line 24VDC power supply, 0---10mA , , 1---5VDC , 0---5VDC output 220VDC power supply, 4---20mA, 0----10mA , 1----5V , 0----5VDC output Nine, installation precautions 1 The cover must be hand-tightened and must not damage the threads. 2 sensitive parts should be tightened. 3 The wiring holes must be sealed with suitable seals. 4 If there is a wiring hole on the electronic housing, it must be plugged and tightened with a threaded plug. 5 The circuit side of the housing and the isolation layer on the wiring side must not damage the ring, and the terminal must be intact.
