MS—H375 Hand Communicator Introduction MS—H375 communication device, it uses Bell202 standard frequency excursion technique, conforming to HART protocol. This communicator MPM486, MDM3051 intelligent pressure with HART protocol; interface nickel-manganese-hydrogen battery power supply, no outer power needed. The communicator is used for local or remote communication conveniently. Basic Function Inspection-self The communicator inspects itself when power on, and searches transmitter as well. Transmitter and Loop Testing Testing function verifies if transmitter, interface and loop are working normally. Configuration Function Setting relative parameter for transmitter. Parameter Relative to Output Display 14 units, calibrate 4mA and 20mA setting value, change linearity or evolution output and input damp. Parameter Un-relative to Output Setting transmitter SN, description signal, date, information, indicator type, isolated diaphragm and port material. Formating Function Adding pressure on sensing part to get one relative value, save this value in HART intelligent transmitter electronic circuit’s EEPROM. Keyboard Function Keyboard includes integrated letter keyboard, 6 special function keys and 3 signal keys and conversion key. MS—H375 Hand Communicator Connection The communicator could connect with transmitter through any terminal in control room or http: //www.microsensor.cn Add: No.18,Yingda Road Baoji,P.R.China, Tel: +86 917 3600739/3600832

MS—H375 Hand Communicator local place or loop, but there should be resistor between 250Ω and 500Ω. Wiring has no polarity difference, please pay attention that terminal must be connected with transmitter two sides or load resistors’ two sides, but not power’s two sides.
