The meter has two rows of LED, the upper one is used to display the measurements 

(PV)  and  various  codes  of  parameters  ;the  lower  one  is  mainly  used  to  display  setting 

value  (SV),  the  output  value  (MV)  or  the  remained  time  of  running(TIME)  and  various 

parameters. When press the DISP SELECT button, the lower screen will show the items 

in the SV, MV, TIME order. When the meter is set as curve process controller (ctrl set to 

prog), TIME shows the remaining time of certain period of procedures. While the meter is 

set  to  constant  temperature  controller,  TIME  shows  cent  code.  In  some  special  type  of 

instrument,  TIME  shows  the  second  group  measured  value  or  special  meaning  of  input 

signals.   

On  the  panel  of  the  meter,  there  are  two  digital  tubes  display  window:  PTN  and  STEP, 

and  four  indicative  lights:  PROFILE,  RUN  etc..  These  two  digital  tubes  and  four 

indicative lights are used to indicate the operation states of these curves. When the meter 

is set to curve procedures controller (ctrl set to prog), PTN is the display window of the 

No. of curve procedure. By pressing PTN button, we can select the curve which needs to 

run or be modified. When the curve is running, RUN blinks, STEP window shows the No. 

of the running curve. When running on the slopes of the increase, the indicator "/" is on. 

When running on the platform, indicator "-" is on. While running on the slope of decline, 

indicator "\" is on. 

When  the  meter  is  set  to  constant  temperature  controller,  the  two  display  windows: 

PTN and STEP, PROFILE, RUN, these four lights were off.   

OUT1 is used to indicate the working state of output 1. It is on when there is output.   

OUT2 is used to indicate the working state of output 2, It is on when there is output.   

SV lights: when the lower screen shows setting value, SV is on. MV lights: when the 

lower screen shows the output value, MV is on.   

TIME  lights:  the  lower  screen  shows  the  remained  time  of  the  operating  procedures, 

TIME is on. AL1 is used to indicate the working state of emergency. When the AL1 is in 

the state of alarm, the lights lit. MAN is used to indicate the state of manual work. When 

working  in  manually  state,  MAN  is  on.  COM  is  used  to  indicate  the  state  of 

communication. When the meter sends data, COM is on. AT is used to indicate the PID 

state. When the meter is in the state of PID, AT is on. OP3 is used to indicate the state of 

output 3, or used as special indicator in certain model. 

c. Button operation 

 

The meter have eight buttons, in which PTN, RUN/ PROG and SET/ PROG these three 

buttons are dedicated to a number of the setting of curve program parameters. When the 

meter is set to curve process controller (ctrl set to prog), PTN is used to set the number of 

curve  program.  SET/PROG  is  used  to  set  operating  parameters,  RUN/PROG  is  used  to 

start  the  program.  When  the  equipment  is  set  to  constant  temperature  controller,  RUN/ 

PROG, SET/ PROG are not working.   

DISP / SELECT is the switch button. When we press DISP/ SELECT button, the lower 

screen  shows  settings  value,  the  output  value  or  the  remained  time  of  operation,  the 

corresponding indicator SV, MV, TIME are on.
