Electromagnetic flowmeter 4-20mA current output zero and full point correction method

2024-07-10

Electromagnetic flow meter can accurately measure the flow of liquid in the pipeline. Through the detection of the fluid through the magnetic field caused by the voltage change, electromagnetic flowmeter can real-time monitoring of the fluid flow rate and flow rate, to help enterprises grasp the production process of fluid flow in real time.

Current zero correction:

1、Access this menu item.
2、Connect the ammeter to the "+" and "-" terminals of 4-20mA on the terminal board, observe the reading of the ammeter, if the current current current is not 4mA, input the value of the current current (positive value) into this setting item, the input mode can refer to the range setting mode, input the value of the current will be adjusted to 4mA automatically. After inputting, the current value will be adjusted to 4mA automatically, if there is still deviation, then continue to input the current current value until the 4mA calibration is completed.

Current fullness correction:

1、Access this menu item.
2、Connect the ammeter to the "+" and "-" terminals of 4-20mA on the terminal board, observe the reading of the ammeter, if the current current current is not 20mA, then input the value of the current current (positive) into this setting item, the input mode can refer to the range setting mode. After inputting, the current value will be adjusted to 20mA automatically, if there is still deviation, then continue to input the current current value until the 20mA calibration is completed.
