Desktop LCR Digital Meters With Automatic Balance Bridge Principle
VICTOR 4090A LCR Meter Desktop Bridge LCR With Automatic Balance Bridge Principle Component Parameter Analyzer
Description
This series desktop bridge incorporates 3.5-inch TFT display, user-friendly interface, and a variety of measurement parameters into one body. It is convenient for users to carry out remote control with USB and RS232 and also perform the sorting of components using handle. In function, it can not only adjust the output frequency and test level, but also record the value of components in the process of measurement. In the performance parameters, its basic accuracy reaches 0.2%. This manual will take “Type A” as an example.
● Measurement frequency up to 100kHz ● Test level 100 ~ 2000mV ● Support the measurement of DC resistance and electrolytic capacitor ● Internal bias voltage output (1mV-1500mV) ● Automatic identification of component measurement ● 3.5-inch TFT display, 5 and a half bits display ● USB, RS232 communication interface, Handle sorting ● Data recording function (maximum and minimum values, average value) | ● Support SCPI communication protocol ● Provide system settings, which can configure language, buzzer, screen brightness, etc according to the needs of users. ● Basic accuracy 0.2% ● Manual and automatic range ● Be equipped with open circuit and short circuit correction ● Comparator has sorting and alarm function ● Provide a variety of test ports |
