The Parameters of  Each channels(Channel menu level)
4 SU+N(1~4) Setting value Set the temperature set value (SV) which is the target value for control Determined by P-SL P-SH  100
5 AL+N Alarm value Please  refer  to ALP for the alarm mode suitable.   0
6 Sc+N PV Bias The value set in the PV bias is added to the actual input value to correct the input value. ±20.0   0.0
7 P+N Proportional band Set when PI or PID control is performance. For heating / cooling PID action.
When P=0,the meter is ON/OFF control
1~100   100
8 I+N Integral time Eliminates offset occurring in proportional control. 0~3000  500
9 D+N Derivative time Prevents overshoot and/or undershoot caused by integral action effect.. 0~2000S  
100S
10 Hy+N Differential gap When the control is ON/OFF control(P=0)
Relay contact may repeat its turning ON and OFF due to input fluctuation if measured value (PV) is near the alarm set value.the differential gap setting can prevent the relay contact from ON or OFF repetition.
