Access to the system parameter setting state
In the basic display state, press and hold key 2 seconds, LOC parameter appears, set the
LOC = 800,Then press the button to confirm and enter the system parameter setting state.
, , Key can directly modify the parameter values. Press the key to reducing
the data, press the
to increase the data,Waiting to modify the value of the decimal
point will flash (like a cursor)
.
press key and hold, you can quickly increase / decrease in value,
And the speed will be automatically accelerated. also press the key to move to modify the
data location (cursor), the operation is more efficient. Key can be stored to modify
parameter values and display the next parameter,press and hold key 2 seconds,and can
return to the previous parameter;
and hold key and then press the key can
immediately exit the parameter setting state.

6.2 Set Value Setting
In basal display status, if the parameter lock “Loc” isn't locked, we can set setpoint (SV) by
pressing first
、
then can press , or to adjust value. Press key to decrease
the value, key to increase the value, and key to move to the digit expected to modify.
Keep pressing or , the speed of decreasing or inscreasing value get quick. The range
of setpoint is between the parameter SPL and SPH.
6.3 “At”PID Parameter auto-tuning
"At" parameter "OFF" is set to "ON" and then press the KEy to confirm instrument can start
the implementation of the auto-tuning Given function,the instrument in the basic display state
display will flash the word "At", the instrument after 2 oscillation cycle ON-OFF control can
automatically calculate the PID parameters.If you want to advance to give up auto-tuning , "At"
parameter “ON” is set to “OFF” and then press key to confirm.
Given tuning parameter values obtained are not identical, to perform auto-tuning function,

The most commonly used value or middle value, if the system
is good insulation properties of the furnace, the given value should be set in the system uses

Execute the start of the operation of auto-tuning function. Reasons to
learn, auto-tuning after the initial use, the effect may not be the best, you need a period of time
(usually the same time auto-tuning control) before they can get the best results.
