VK3BHR LC meter inductance measurement problem
I have replaced the inductor L with the TDK part, 100uH, 0.7ohm, 2MHz SRF. Also replaced both C and Ccal with 1% polystyrene capacitors. Removed the relay to a separate PCB (thinking that Relay coil might be interfering with 100uH inductor). Now the circuit is working as it should. Thanks to all for their valuable feedback to make this a success.
