FEATURES OF HAND OPERATORS
1、During online monitoring and communication, modulation signals will not interrupt 4-20mA DC signals;
2、Can be used together with instruments using the Hart communication protocol. The Hart communicator can be used together with instruments using the Hart communication protocol;
3、Easy to operate large display screen (4 lines, 18 characters per line), using Chinese display, making it easy for users to see at a glance, and
convenient for setting and changing.
Information self diagnosis/protection function
1、Full function communication: communication with flow meters, temperature meters,pressure meters, and liquid level meters using the HART protocol;
2、Large screen display: The display interface is larger and clearer;
3、Can perform production testing, diagnosis,and inspection on HART devices;
4、Can configure, calibrate, diagnose, maintain,and monitor HART devices during on-site operation;
5、Obtain manufacturer information of on-site HART instruments;
6、Understand the working status and fault information of HART instruments;
7、Read the output current and process variables of the instrument;
8、Obtain parameters and output values related to the sensor.
Self checking function；formatted password protection；low voltage alarm display
