Below the accuracy graphs of my unit ET432.
Just to complete, the accuracy graph for a 10Mohm metal film resistor.
As expected, excellent behavior up to 40kHz and -8% drop at 100kHz (but still within spec.).
What to say more? The instrument is not very performing @ 100kHz for resistance values higher than 1Mohm.
However, in my opinion it remains an excellent LCR analyzer!!
More, the manufacturer provides a very complete user manual, full of information especially in relation to the accuracy of all the parameters measured by the instrument.
This is another plus point that should not be underestimated...
