If you choice "non" in - and press to enter then - will not display anything but if you choice other parameter in -, it will display which parameter. The operation in - to -, - to - and - to - all are the same.

How to modify input This series controller provides free input for T/C and RTD, it doesn't need to modify hardware except analog input..analog input hardware modification (Refer to S~S8 on PC board back) S & S are shorted with COM. originally, so it needs to open S or S& S and to short some pads as drawing. INPUT TC/RTD ~MA ~MA ~MV ~V ~V ~V ~V S S S S S S S S8 [ ] short [ ] open.analog input software modification Select "Lin" in "inpl" parameter Set "LoAn" in "inp" level to lowest range Set "HiAn" in "inp" level to highest range all parameters are locked except PV all parameters are locked except SV open"user" level and above open"cntl" level and above open"out" level (Except OUTM )and above open"i NP" open"spc" level and above level and above open"prog" level and above open"hide" level and above open"user" and "PROG" level only.analog input calibration Enter "ALS" parameter in "inp" level Provide signal for lowest range and wait for sec then keep pressing key Enter "AHS" parameter in "inp" level Provide signal for highest range and wait for sec then keep pressing key Return to PV/SV initial and provide signal for lowest range again then check if PV equals to LoAn Provide signal for highest range again then check if PV equals to HiAn If it is not accuracy after calibrating, please repeat above procedure again P.
