maximum range of impedance measurement

After going through the cal procedure it is worthwhile checking the impedance of a sample resistor or two (preferably a separate 1% resistor not used during cal, and perhaps of value a decade below and above the reference resistor value). If the impedance plot is flat for impedance and phase and within 1-2% of expected value then you should be fine for basic capacitors. How are you 'identifying' the test capacitor as '60+nF'? You can click the mouse on the impedance plot at a selected frequency and read the bottom left calculated value (best to do that at the frequency used by the LCR meter if you want to compare those two measurement techniques), as well as use the component model function (which requires the part to exhibit certain impedance characteristics over a given frequency span).
