If you leave the test leads open and push the ZERO button, it works fine for
cap zeroing. Short the leads and push the ZERO button for inductor zeroing.

Dear AADE LC Meter IIB users,

I am also very fond of this nice LC Meter but I have a question:

When I have pressed the button for measuring inductors and the circuit is
open, the meter reads: "Not an  inductor". But when I press the button for
measuring capacitors and connect both test imputs, only once I remember to
have seen the indication: "Not a capacitor" (or something like this).

But in general, when shortcircuiting both inputs, I get an unstable pF
reading; it seems that under these conditions the oscillator operates in an
uncontrolled mode because it is forced to work with a rather low parallel
inductance. This does not really bother me, but I guess this behaviour is
not intended.

Is this problem still existing or has it been cured now (perhaps by
introducing another resistor or capacitor which dos not allow any
oscillations under these conditions)? I have my LC Meter already in use for
several years.

HW?
