LCR6200 inductance meter

Hi,
Do you know what source resistance to choose..its either 30R, 50R, or 100R?
Also, what does the "L force" input mean?
Also, "H force"?
I measured some inductors but its well inaccurate.
I  did all the opan and short calibration/initialisation steps.

Do you work with kelvin probes ?   show photos of your probes

the "L" side  will touch together on one side on the part to be measured

Same for the "H" side

Unless some damages happened ?

I am getting a Lsec measurement of 7.5uH...and primary of 480uH.
Thats 8:1 and it surely cant be that much in this design.
I am wondering if the intercoil capacitance is making the sec coil inductance look much lower than it really is.?

The Sec coil, with the "Ls-Q" measurement comes out as 7.5uH and Q=12.
Q=12 sounds high, i am wondering if there is loads of intercoil capacitance and the inductance reading is thus coming out low.
