"PV" should be show 80% of full pressure range .
For example:
the current
“PV” shows "00.00", full pressure range set to “10.00”
Press "CAE", the "PV" shows "8.00".
The functional role :
if "PV" shows deviation is too much , the instrument need to calibration;
If
“PV” no change, can be initially determined sensor is faulty.
4.6)
Using CAE calibration the instrument zero / span (only applicable to pressure
sensor with a calibration line)
Sure has been properly connected pressure sensor, and the current no pressure status;
In working state, instrument according to the instructions by 4.1 first, adjust to manual control status ;
press the "MODE" and "CAE" button at the same time, until the "SV" shows "0028", then loosen the button;
"SV" shows a digital countdown, timing to zero, zero span end of calibration.
4.7) Modify the user password
In working state, instrument according to the instructions by 4.1 first, adjust to manual control status ;
press the "MODE" and "A/M" button at the same time, "PV" shows "PASS";
Press the "<" adjust "SV" Numbers flashing, flashing a is modified;
press "
∧
" or "
∨
" adjust the flashing value up to down ;
After enter the password, press "SET" to validate (initial password: "0000");
Password authentication is passed, enter into new password Settings, "PV" shows "NPAS";
Press the "<" adjust "SV" Numbers flashing, flashing a is modified;
press "
∧
" or "
∨
" adjust the flashing value up to down ;
After setting the new password, click "MODE" button to return to work.
Notice :

password. So once the user changed the initial password, please your new password . If lost the new
password and cause parameters can be setting problem, the user need to ship back the instrument to the

4.8) pressure control target value setting (SV setting)
In working state, press "SET" once, "PV" shows "SV" ;
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 proportional
band (P) parameter Settings.
4.9) proportional band parameter
“P” settings :
In working state, press the "SET" twice, "PV" shows "P";
Press "<" to adjust "SV" Numbers flashing, flashing a is modified;
press "
∧
" or "
∨
" adjust the flashing value up to down ;
