    АМM-3320 Function Descriptions 1. Parameters setting Press FUNC. key to select the following parameters sequentially: AUTO LCR, L-Q, C-D, R, DCR. Parameter Meaning AUTO LCR Auto LCR smart mode Inductance measurement，the parameter on sub-display is quality factor Q. Capacitance measurement, the parameter on sub-display is dissipation factor D.
  • Page 14 АМM-3320 If θ > 11°, the Auto-L mode is selected. The parameter on sub-display is Q. If θ < -11°, the Auto-C mode is selected. The parameter on sub-display is D. If the C < 5pF, the parameter on sub-display is parallel resistance Rp. Note: In order to avoid damaging the instrument, the capacitance requires discharge before measuring.
