5.2 Selection of parameter
5.2.1 Selection of frequency
ET1080 Series handheld LCR applies AC test signal to the DUT for measurement.
Frequency is one of the main parameters of the AC source. Due to the presence of the
non-ideal and distributed parameters of elements, and the impact of the distributed
parameters between the test end, the same element may have different results with
different test frequencies. Therefore, before the measurement the appropriate frequency
should be selected.
There are two ways to change the test frequency:
Method One: press FREQ to switch between different frequencies.
Method Two: Press the right and left arrow keys to select frequency on the interface
as shown in figure 5, and press the up and down arrow keys to switch frequencies.

5.2.2 Selection of level
This Series handheld LCR applies AC test signal to the DUT for measurement. Both
the frequency and signal level can be changed.
There are two ways to change the test signal level:
Method One: press LEVEL to switch between different test signals.
Method Two: Press the right and left arrow keys to select level on the interface as
shown in figure 6, and press the up and down arrow keys to switch levels.
