instrument. 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. -

By correcting it can effectively reduce the error of distributed parameters caused by the test line. The short circuit correction can reduce the impact of the contact resistance and lead resistance on the measurement of low impedance element;... -
Page 15: Resistance Measurement
Do not measure the charged capacitor, or it may cause damage to the instrument. In case of measurement of on-board devices, make sure the power is turned off. The active circuit cannot be measured directly. When used in the dusty environment, the instrument is easy to gather dirt, so it should be cleaned periodically to protect the test port to prevent the dust from entering the instrument. -
