Input-output signal calibration
Other calibration operations such as input signal, output signal calibration method (figure 14)
After the factory generally do not need this operation, if you need to use under the guidance of engineers！

1.Input Signal calibration
①.In the normal measurement and control state of the locator, press A/M key for about 4 seconds, will enter the set parameter state, display “UO”parameter value. By pressing the A/M key, select the “U 5”parameter. Press ▲、▼ to change the value of “U 5”to o 11.1; (see table below for numerical implications)
②.Enter “U 8”parameter value for calibration input current zero: calibration, through external instruments, input zero signal (generally 4mA) , press A/M key to confirm, then enter “U 9”parameter;
③.“U 9”parameter is calibration input current full range: When calibration, through external instrument, input full range signal (usually 20mA) , press A/M key to confirm, then enter “U 5”parameter; modify U5 = 000.5, press A/M key to confirm exit, calibration is completed.
●The above operation ensures that the input signal is clean and stable

2.Output Signal calibration
①.Enter U 5 parameter, modify, U 5 = 001.1, press A/M key to enter U 6 parameter, Skip U 6, U 7, U 8, U 9 to Enter Ua;
②.“Ua”for calibration output current zero: calibration, operation ▲、▼ key, make calibration output for 4 Ma or other values, corresponding to the actuator zero output signal value, press A/M key to confirm, then enter “Ub”parameter;
③.“Ub”parameter for calibration output current full range: operation ▲、▼ key, make calibration output for 20mA or other values, corresponding to the actuator full output signal value, press A/M key to confirm, then enter “Uc”parameter.
④.“Uc”parameters for the correction shell temperature, operating ▲、▼ key, can be adjusted;
Press A/M key to confirm, then return the “U 5”parameter, modify the “U 5”value, U 5 = 000.5, press A/M key to confirm, return the status of measurement and control.
