Iout 4-20/0-20mA debug process

Environment and parameter check
To confirm if the power supply works fine.
To confirm if the data on the LED screen is transferred to the system.
To confirm if the Iout function is still on.
To confirm if the low point value is 0 or 4mA.
To confirm the setting of the corresponding value range.
To confirm if wire wiring is correct and the insulation of unused wires is finished.
Hardware, wiring, and program of the receiver check
If the wiring during the above test is different from the actual operation, please re-test.
Exporting of the device check
Separating the Iout wiring from the system, then using the multimeter MA stalls to confirm if the current export works fine.
Results and actions
If the data is still abnormal when both the Iout export function and the equipment and program of receiver work fine, some other possible reason, like pipe size, or paddle wheel abnormal, should be checked further.
The current device may be damaged possibly. If users have another device for cross test, please make sure receiving equipment, data processing program, or wiring work fine.
Contact the original manufacturer with the serial number, wiring diagram (all related wiring of the flowmeter), and the model and brand of receiver.
Make sure if receiving equipment, data processing program, or wiring work fine.
To get into to check if the 4/0mA export and interpretation function of the receiver (If there is a difference between data to data, users could adjust it by the unit uA at this page) works fine.
To get into to check if the 20mA export and interpretation function of the receiver works fine. (If there is a difference between data to data, users could adjust it by the unit uA at this page.)
To confirm if the interpretation function of the receiver works fine under simulation mode when testing different data. Simulation mode must be switched off when testing is finished. (Users can switch on the simulation mode by too, and adjust the simulated data by . Back to the main page while finishing data adjustment.)
