Overshoot limit, during PID control process, when PV(measured
value) > SV(set value) + OVS(overshoot limit), force to close output.
The smaller this value is, the smaller the PID adjustment range is,
the worse the control stability is. Please set the appropriate value
according to the actual situation.This function is unavailable when it is
set to 0
Differential time:The system oscillation can be
prevented by reducing the differential action to a
suitable value. The larger the value is, the stronger
the differential action is. Unit: s
Integral time, the smaller the value is, the stronger the integral action is,
otherwise, it is weeker. and the more it tends to eliminate the deviation
from the set value. The deviation may not be eliminated if the integral
effect is too weak. Unit: s
Proportional band: the smaller the setting value is, the faster the system
responds; otherwise, it is slower.Increasing the proportional band can
reduce the oscillation, but it will increase the control deviation. Decrease
the proportional band can reduce the control deviation, but it will cause
oscillation. Unit: corresponding measured value

occasions, it can get a more stable control display value,
this value is unrelated with actual measured value. Note:
after setting this value,when alarm setting value is equal
to SV setting value, alarm output operation is subject to
actual measured value. Set as 0 to close this function.

PID algorithm option:0(FUZ): Advanced fuzzy PID
arithmetic; 1(STD): normal PID arithmetic
Setting parameter reserve position: 0 (EEP):EEPROM
with power failure protection; 1(RAM): RAM without power
failure protection. Description of setting parameter storage
location: EEP and RAM. EEP means that the setting
parameters are written into EEPROM and can be
permanently saved after power failure.It is generally used
for factory setting parameters of equipment. Because
EEPROM has the limit of writing times, too many and too
frequent writes will be damaged;RAM: it means that the
parameters are stored in RAM without writing limit and will
not be damaged due to frequent writing. The parameters
set after the equipment is powered off will not be saved.
After power on, they will be restored to the parameters
saved in EEPROM by the equipment manufacturer.It is
usually used for frequent parameters writing when
communicating with the upper computer PLC.
The method of using this parameter is to set this parameter
to EEP first. After the equipment factory has finished debugging
the equipment and set the parameters, the parameters
are saved in EEPROM, and then PRS is modified to RAM,
and the equipment is delivered to the user for use, so as to
prevent erroneous modification or long-term communication
writing data from damaging the EEPROM.
RUN/STOP reserve position: 0 (EEP):EEPROM with power
failure protection;1(RAM): RAM without power failure protection.
this parameter method: if the instrument is required to be in stop
mode every time when it is powered on, first set RSS to EEP,
and then set "start stop operation" = STOP. This setting parameter
will be saved for a long time; Then set RSS to RAM. When using,
the upper computer starts/stops the instrument, which is stored in
RAM. After power on again, the instrument still enters STOP mode.

controls exceeds the total power limit value; Unit: kW; Set to 0,

1. Monitoring mode operation(RUN/STOP)
1）SSM is set in open meter operation; Otherwise, the settings only be modified during communication.
2）Under the measure mode, long press “ ” key to enter the STOP mode, SV window will display
“STOP”, main control output will stop or keep the minimum output.
3）Under STOP mode, long press “ ” key to exit STOP mode, press “ ” key to modify SV value.
4）Under STOP mode, alarm output and analog output work normally.
2. PID auto-tune operation:
1）Before auto-tune procedure, please switch off the control output load power, or set the meter as STOP
mode.
2）Before auto-tune procedure, PV value should meet below condition: when it is PID heating control, PV
needs to be much smaller than SV; when it is PID cooling control, PV needs to be much larger than SV.
3）Before auto-tune procedure, please set a proper alarm value or eliminate the alarm condition, in
order to prevent the auto-tune procedure from being affected by alarm output.
4）Set PID type and SV value; the factory default setting is fuzzy PID.
5）Set as PID control, if there is OLL & OLH output limiting, please set the output to a proper range;
factory default setting is OLL=0%, OLH=100%.
6）Exit STOP mode, or switch on the load Power, immediately long press “ ” key to enter auto-tune
mode, then the AT indicator light is on.。
7）The auto-tune procedure will take some time, in order not to affect auto-tune result,please don`t modify
the parameters or power-off.
8）When AT light goes out, it automatically exits auto-tune mode, PID parameters will be updated
automatically, and then the meter will control automatically and exactly.
9) During the auto-tune procedure, below actions will cause the termination of the precess, long press
“ ” key, measure beyond the scope, abnormal display, switch to STOP mode, power-off, etc.
10）Note: In the occasions with output limiting operation, sometimes, even if the auto-tune is carried out,
the best PID parameters still cannot be obtained.
11）Experienced users can set a proper PID parameter according to their experience.
