I have a three-phase circuit in which all the possible components that have a modifiable frequency setting have the frequency 50 Hz set. Some of those components used to have $(freq) as the frequency value, which is assume points to somewhere. Unfortunately, I didn't find the place where it pointed so I just put a raw numerical value in every component in the circuit.
The circuit works properly and the only problem is that the multimeter is displaying the value 60 Hz as the frequency. I have single-phase ammeters, right after the multimeter, which output a signal that is in 50 Hz, hence the circuit ought to be working properly, at least in that regard, and the multimeter seems to be therefore displaying the wrong frequency.
Here is a picture of the circuit with arrows pointing to the ammeters and multimeter:
So the question is:
Why does the multimeter show the wrong frequency?
How can I change the value that $(freq) points to?
Thanks in advance!
