1. Summary

YK-19 series intelligent Channels Measurement instrument is intelligent, high accuracy controller for temperature, pressure or level measurement. When use it to equipped with temperature, pressure or level sensor, we can consist temperature, pressure or level measurement control system for various type and range. provide

RS232 or RS485 to communication with computer or PLC。The instrument has a real-time clock for user get date and time。

3. Operation

Key-press Description

Press the KEY to mute the Buzzer.

at setting parameters state, press the key return to work state. At work

state, press the key to switch cycle display and static display. While at cycle display state,the bottom LED are display –xx-, at static display

。

Press the SET key to enter setting status.，After chang the current parameter

at setting parameters state, press ▲key making parameter increase one.

and hold the ▲key, value will increase or decrease quickly and release for stop. At static display state, press ▲key will change to next channels value display.

at setting parameters state, press▼key making parameter decrease one. and hold the ▼key, value wil decrease quickly and release for stop. At static display state, press the key will change to next channels value display.

After power on the display window displays HELO to indicate self-checking is right, displays -HH- indicates input over range or sensor disconnection or short-circuit. Instrument adopts man to machine talk model for input parameter, and use various prompting to indicate what kind of data should input. At the work state, the up LED display measured value,the bottom LED display the number of the corresponding channel.The last two are the date(-Ht-) and time(-Lt-).

(1)press the En key, the up display window displays –Cd-,bottom LED will display 800, Only 800 is changed to 808, and then press En key again will make the instrument to access the setup parameter setting status, other value is denied for preventing field operators from set parameters incorrectly by mistake.

(2) -LP-: the instrument measuring the number of channels,rang:1~16, Factory default 10.

(3)1-Sn：the first channel intput sensor type,Reference the table below,Factory default P100.

Rang 0-3,Factory default 1.

(5)1-PL: the 1st channel lower range value, only for the first,it is lower range value for the transmitter output too.

(6)1-PH: the 1st channel higher range value, only for the first,it is higher range value for the transmitter output too. For example,1-PL=0.0,1-PH=300.0, first channel measured value is150.0,then the output 4-20mA value is 12.0mA.

(7)2-Sn：the 2nc channel intput sensor type.

……

(8)1-HA: the 1st channel ultra-high alarm value.

(9)1-LA: the 1st channel ultra-low alarm value.

……

(10)1-Eo: the 1st channel measured value deviation rectify.ex: actual the 1st value is 30.0, currently display value is 29.2,then the parameter 1-Eo=0.8.Factory default 0.0 (11)2-Eo: the 2nd channel measured value deviation rectify.

……

(12)Addr:the communication address for computer, rang 01～99。Factory default 1
