6.1 System parameter setting
In the basic display state, press and hold key 2 seconds, , 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 i
s 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; can immediately exit the
parameter setting state.
Enter the field parameters

press and hold key 2 seconds
6.2 Set Value Setting
In the basic display state, press , , key can directly modify the given value.
6.3 “At”PID Parameter auto-tuning
Press and hold for 2 seconds, the At parameter appears,"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 ide
ntical, to perform auto-tuning function,
should be first given value set in 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
the maximum, and then 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.
