RuoShui 4090 Digital LCR Meter Desktop Capacitance Resistance Impedance Inductance Measure Instrument Electric Bridge Component

Descriptions:

VC4090 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%.

Features:

● 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

minimum values, average value)

● Support SCPI communication protocol
● Provide system settings, which can configure
language, buzzer, screen brightness,
etc accordingto 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
