Hello,

I want to realize this LCmeter that measure the inductance and capacitance of a connected dipole
But my simulation in ISIS does not work, I think this is due to the relay that does not work and I do not find how to solve this problem
help me please
here is attached the project folder with the program source code

Construct a simple circuit which contains the relay. Test its operation. Run different amounts of current through the coil.

Observe how much current is needed to activate it.

Also observe how much coil current can drop, before it releases.

These experiments will tell you the specs for controlling its operation.
