Handheld intelligent operator

1、 Overview of Handheld Intelligent Operators
The handheld intelligent operator adopts a dedicated chip, which is a successful application of the latest communication technology, digital technology, and integrated electrical technology. The initialization and daily maintenance of isolators, transmitters, distributors, and conditioners are used to set parameters such as zero point, full range, linearity, input, output, and alarm points for such instruments. The process is very convenient and fast.
2、 Characteristics of Handheld Intelligent Operators
1. Accurately display the process quantity and working status of online instruments in communication state.
2. Real time calibration of the input and output signals of the "display unit" and "loosening unit" series instruments of Jiechuang Instruments.
3. Real time setting of communication methods and machine numbers for instruments.
4. Powered by a regular No. 5 dry battery, it is easy to source and replace.
3、 Handheld intelligent operator display


Digital tube
In non communication state
1. At the beginning of power on, after the instrument model is displayed, dual row digital scanning enters the communication waiting state.
2. When entering the operator setting state, the upper row displays the operator parameter code, and the lower row displays the specific parameters.
In communication state
1. When the instrument is connected to the machine, according to the function of the connected instrument, the measured value (process quantity) of the instrument is displayed, and the control quantity under the adjustment function and the two process quantities of the main and auxiliary inputs are adjusted.
2. When entering parameter settings, the upper row displays the parameter code of the instrument, and the lower row displays the parameters.
Alarm lamp
A: First state alarm light
E: Second state alarm light
B: Third status light
D: Communication status light: The D light flashes rapidly when the instrument is in communication mode;
Fault light: When the instrument input signal is in a fault state, the D light flashes rapidly to indicate the communication status, and then flashes slowly.
