1st alarm value, note: the minus is dealed as absolute value when it is
as a deviation value .
Set range Factory setting
1st alarm hystersis
1st alarm mode . Note: when 1st alarm is used as OUT2 , should set
as 0. When setting as 0, it close alarm function. When set value ＞6，
should set AD2 as 0. (refer to alarm output logic diagram on page 6)
2nd alarm value,note:the minus is dealed as absolute value when it is as
a deviation value .
2nd alarm hystersis
2nd alarm mode. Note: When AD1＞6, should set this value as 0 to
close the alarm function.(refer to alarm output logic diagram on page 6)
Amend value,display value=actual measured value+ amend value
Optional input measured signal type:refer to input signal parameters
table.Note:it need to change the relevant parameters after changing.
Proportional band,the lower of setting value,the faster of system heating .
Increase proportional band can reduce vibration,but it may increase control
bias.Reduce proportional band reduce control bias, may cause vibration
Integral time the lower of the value,the stronger of integral action,the more
tendency to eliminate and deviation of set value.If integral action is too weak,
it may not eliminate the deviation. Unit: Second
Differential time,reduce effect of differential time to proper value,which prevent
system oscillation.The higher value,the stronger function of differential.Unit:s
Overshoot limit,in the process of PID control,when PV>SV+OVS,it force off
output; The lower value,the lower PID adjusted range,the worse control
stability;please set a proper value according actual state.
On-off control backlash(nagetive backlash on-off control) or cooling control
and compressor cooling control dead zone. please change value according
to decimal position,when you change input sigal type type.
OUT1 heating control cycle, 1:SSR control output,
4-200: relay control output. (Unit:second)
OUT2 control cycle,cooling relay output cycle.Unit:second
OUT2 cooling proportionality coefficient,the higher of value,the stronger of
cooling

PV fuzzy tracking value,it can get stable control display value in some status.
Note:when the alarm setting value is equal with SV setting value after setting
the DTR value,operation of alarm output is subject to actual measured value.
Setting 0 to close the function.

1: meter enter into pid auto-tuning status after power on. long press
Key function operation
1. Run/stop operation
1）Under the measure mode,press “ ” into monitoring mode;and on the SV window display “STP” . Long Press “ ” to exit.
2）It can modify SV value and shift mode operation even if displaying STP.
3）Under the monitoring mode, main control output will stop
2. PID Parameter confirmation and auto-tuning operation:
1）Factory default PID may not be suitable to usage occasion;please use auto-tuning function to get suitable PID setting.
2）The meter will make control output after power on a short period. User can set the meter to monitor mode to make sure
auto-tuning effect, or switch off the power of control output load at temporary . No matter how to operate, it should guarantee
the set value is larger than the present measured value, it is better if much larger.
3）In order to avoid the effect of alarm output,please set the proper alarm value,or remove the alarm effect.
4）Set proper SV value .
5）Set OT as 1 (PID control).
6）Under the condition of PV value at normal room temperature, exit the monitoring mode or switch on load power,and
long press “ ” to enter auto-tuning mode, and AT indication light will flashing.
7）Auto-tuning need a period, to ensure the auto-tuning result,please don`t modify parameters or power-off during auto tuning.
8）When AT light is off , it will exit the auto-tuning. PID will update automatcially, and can get good control result.
9）During auto-tuning, long press “ ” key, measure beyond the range,display abnormally, shift to “STP” status,power-off
ect will stop the auto-tuning.
10）Experienced users can set a proper PID parameter according to their experience.
3. PID & Cooling control operation (suitable for injection molding machine , extruding machine ect)
1) Please set OT parameter as 3
2）PID control act on main control output OUT1；Cooling control act on OUT2.
3）AL1 alarm relay will be used as OUT2 control output.
4）Please set the cooling start offset DB to a value bigger than 5,to ensure the cooling would not affect the PID control impact.
5）Please set cooling control cycle CP1 to a proper value,and modify the cooling proportional coefficient to a a proper value.
6）When PV value > SV+DB value,the cooling control start to effect;the bigger value of PV,the longer output time of OUT2
