Low-Z high-accuracy mode for increasing the maximum applied current
When using low-Z high-accuracy mode, the output resistance changes to 10 Ω, allowing more current to flow to the sample being mea-
sured so that high-precision measurement is guaranteed.

Low-Z high-accuracy mode can be used with the 100 mΩ, 1 Ω, and 10 Ω ranges.
This mode is especially effective when performing low-inductance L measurement of power supplies and ESR measurement of aluminum
electrolytic capacitors.

Improve measurement precision with the waveform averaging function
The IM3536’s waveform averaging function lets you set the number of measured waveforms for each frequency band deter-
mined by the measurement speed setting (FAST, MED, SLOW, SLOW2).
