Description
Every capacitor on your bill of materials claims a value, and an LCR meter checks the claim. The Keysight E4980A LCR meter covers 20 Hz to 2 MHz with a listed basic impedance accuracy of 0.05%. It measures 16 impedance parameters. Lost in HCM lists it for rental and sale in Vietnam.
Checking parts before they reach the line
Incoming inspection needs speed as well as precision. The fast mode takes 5.6 ms per point at 1 MHz, so a production station can sort parts quickly. Meanwhile, engineers in a lab can sweep one part across frequency to see how it behaves. Open, short and load correction then improves results measured through a fixture.

Keysight specifies the accuracy under defined conditions. Therefore, read those conditions in the manufacturer documentation before you set a pass limit.
What it measures well
Typical jobs include capacitors, inductors and resistors. The meter also handles ESR and dissipation factor, which matter for power and filter parts. Semiconductor C-V work and material measurements fit its range too. In addition, programmable list sweeps characterize a part across both frequency and stimulus level.
Bias and fixtures
An optional power and DC-bias enhancement supports measurements on stressed devices. However, fixtures, cables and bias accessories vary by unit. List the part sizes and lead types you test when you ask, so Lost in HCM can match the right fixture.
Rent or buy the Keysight E4980A LCR meter
A rental covers a qualification project or a short production run. A purchase suits a bench that tests parts every day. In both cases, request a quote from Lost in HCM. For other options, see the impedance and LCR meters category, the Keysight website or contact SMK Vietnam.
