modifing status. The way of modifing SV value is same as that of modifing
menu parameters.
g. In the normal measure control mode, long press “ AT ” key more than 3s to
enter auto tune state. During auto tune, PV value needs to be lower than SV

※When the alarm value with deviation alarm is set as a negative number, it will be
dealed as an absolute value.
1. Stop mode
1)Under the measure mode, long press “ R/S ” key to enter the STOP mode,
SV window will display “STOP”, main control output will stop or keep the
minimum output.
2)Under STOP mode, long press “ R/S ” key to exit STOP mode, press “ ”
key to modify SV value.
3)Under STOP mode, alarm output and retransimition 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.

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.
