4.15) Output amplitude low limited value settings
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 .
Press “SET “once again , enter into output amplitude low limited value settings , “PV “shows “OL-L “.
Press "<" to adjust "SV" Numbers flashing, flashing a is modified;
press "∧" or "∨" adjust the flashing value up to down ;
Setup completed, press "MODE" button to return to work, or press the "SET" button enter into Transducer
pressure range value settings .
For example : if the controller output is 0-10v , Output amplitude high limited value setting “10.0”; then
the controller output maximum value will be 1V , no matter manual or automatic adjust , the controller
output value is not less than 1V .
In the manual control , is not subject to this value, the lowest drops to zero.
The functional role: to prevent discharging stuck, instantaneous pressure caused by the phenomenon of
downtime. The exact value setting , need users according to the actual usage Settings.
4.16 ) Transducer pressure range value settings .
Instrument range should be match with the instrument range setting value , then it will display the properly
pressure value . so firstly check the transducer range, if such ranges does not match, follow these steps.
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 “twice , enter into transducer pressure range value settings , “PV “shows “ED “.
Press "<" to adjust "SV" Numbers flashing, flashing a is modified;
press "∧" or "∨" adjust the flashing value up to down ;
Setup completed, press "MODE" button to return to work, or press the "SET" button enter into Decimal
point location settings .
For example : if the controller current range is “10.00 “, and transducer pressure range is 15MPa ,
according to the above steps, and setting the controller range to "15.00".
4.17) The decimal point location settings
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 “three times , enter into decimal point location settings , “PV “shows “DOT “.
Press "<" to adjust the decimal point location ;
Setup completed, press "MODE" button to return to work, or press the "SET" button enter zero/ span value
settings .
