100Hz to 10kHz Handheld LCR Meter
ET400 Series handheld LCR is a portable hand-held measuring instrument for measuring the param ers of inductors, capacitors, resistors and other components. It is small with a 5V lithium battery, suitable for table-type application. It is also portable and mobile.
ET400 Series provides a resolution of four and a half digits for main param ers and a resolution of 0.0001 for secondary param er. Its highest measurement frequency is 100kHz, and can measure the level of 0.6Vrms, 0.3Vrms, and 0.1Vrms. Its automatic range can display the results in the fast, medium, or slow mode. It can automatically select the appropriate measurement param ers according to the characteristics of the component. Its measurement accuracy can reach 0.2%. It combines the convenience of a handheld instrument and good performance of a table-type one.
The operation is simple, and users can see the test frequency, param ers, and speed by pressing the corresponding key; it also has the recording mode to take readings; the convenient operation of open and short circuit correction function helps improve the measurement accuracy. The buzzer, automatic power off and languages can be s on the configuration menu.The standard instrument is equipped with remote communication function. The remote control and data acquisition are achieved by connecting it to the PC through Mini-USB cable.
