Change the type of the sensor by choosing "Current". Choosing any type of sensor does not affect sensor properties, it only changes the sensor icon for the comfort of usage.
Change the name of the sensor, for example, "AC current".
How to use an "Expression formula": 20 * (x-B). "B" indicates the voltage at the output of the current transducer at zero current.
To measure "B", measure the readings of the monitoring system at zero current in the transducer. Typically B is about 0.017 - 0.021.
Then you can write the formula "20*(x-B)". Push OK.
Now the system is ready to measure the current in the transducer core.
Finally put in the threshold levels by dragging: Low alarm, Low warning, High warning, High alarm levels.
For example, the graph above shows that the state of the sensor at the moment is "Normal" because 20.4 is between "Low warning" and "High warning" states, which is considered a "normal" state.Click “Save” on a diskette at the bottom right of the “Properties” window. The page will reload and the sensor will update by changing its icon type to
(abbreviation from "Ampers").
