The output of the Chuanyi electromagnetic flowmeter remains at 4 milliamps
Thread Content
The table header displays correctly, but the output in milliamps is always 4 milliamps! The forced analog signal is also 4 milliamps!
Check the instructions to see whether an active or passive signal is required, and whether it needs to be superimposed
Is it in “circuit verification” mode?
If it is in circuit test mode, simply turn off the power. If it’s passive, there should be no current flow; it’s also impossible for the Hart address to be set to a non-zero value
Check whether Chuanyi supports the Hart protocol; if not, use BT2000 to connect. It seems that your settings are in circuit verification mode, so the output is forced to 4 mA
