4.18) zero/ span value settings .
This operation will cause the collect data is not accurate, please strictly according to the following
instructions:
Make sure the transducer connection is correct, and the current for no pressure status ;
In working state, press the "SET" once ,
” PV” shows “ SV ” , then loosen the button .
Press
“ SET “ again for 5 seconds , it will enter into output amplitude high limited value setting , “ PV
“ shows “ OL-U “, then loosen the button .
Then Press
“ SET “ four times , enter into zero/span value settings , “ PV “ shows “ ESCL “.
Press "<" to calibration zero , controller enter into signal load status ,
“ PV” shows “ LOAD ” .
Load the signal ,
“ SV “ shows value will be changed ( you through add pressure to load the signal)
After load signal finished , press "<" enter into full value conversion settings ,
“ PV “ shows “CNFN “.
Press "<" to adjust "SV" Numbers flashing, flashing a is modified;
press "

For example :
according to the 3 settings different value , The first pressure alarm (AL-1) value, the first
pressure alarm function (SEL1 ) and the first pressure alarm hysteresis zone ( HC-1)
Example 1 :
if setting the AL-1 as
“5.00 “ , setting the SEL-1 as “HJ” , setting the HC-1 as “ 0.20 “ .
In working state, AL-1 relay working status as following :
