NO the Coil is NOT in circuit for this test.

""The final USB-2 cable to the circuit should be used and wires should be kept short as possible.
Ideally, they should be placed inside the coil shells and the bottom coil should be secured. Power on
the TGSL and adjust coil overlap while measuring the open ends of the Rx coil with a DVM in the A.C.
setting.
The goal is to find a sharp null in the voltage reading . You should be able to get the signal
down to about 4mV but the actual reading may be subject to the frequency response of the DVM
used.""
