Program segment control setting method
1) There are total 50 programmable segments. For each segment, there are 2 settable parameters: SV , ST .
2) SV value is the object control value of a segment, for example, if SV 01 is 200, the object control value of
this segment is 200
3) ST value is the control mode parameter of a segment.
When ST setting value is -51, it means it has finished this time’s programmable segment control, reset to single setting
value control mode (refer to example onw)
When ST setting value is -50 -1 it means the current segment will jump to the appointed segment, for example,
if ST -45 it means the current segment will jump to segment no.45 directly, after the control of this
segment is finished.
When ST setting value is 0 it means the program segment will jump to the next segment automatically when the
temperature get to
When ST setting value is 1 1440, unit is Minute, it means when runing within this segment, it will reach the setting value with average
speed; The meter will stop this segment’s operation when this segment’s ST value countdown to 0, if the ST value has already come to 0, but PV
measuring value does not meet with SV setting value, the program will not leave this segment until SV=PV. For example: SV =200
ST =10 the temperature is 30 ,the program will still runing in this segment for 10 minutes and the temperature will rise 17 per minute.

program segment control.
5) In normal display status, press key for a few seconds to enter into status setting value of program
segment control. You can choose RUN, STOP and HOLD three status in this segment.
Example Here is a control process with below requirement, the relevant setting is on the right side:
1) Temperature raise to 300 SV01=300 ST01=0;
2) Temperature raise from 300 to 500 (raise 10 degrees/ min) SV02=500 ST02=20
3) Temperature falls to 150 SV03=150 ST03=0;
4) Temperature is keep at 150 for 60 minute, and then SV04=150 ST04=60
Program jumps to No.10 segment ST05= -10
6) Temperature falls to 25 at No.10 segment SV10=25 ST10=0;
7) Program control stops running at No.11 segment.
exit the segment and control the temeprature according
