brief introduction
■ adopting the latest technology & high density circuit design and concentrating the essence of lcr test, th283x series is a new generation compact lcr meter of low cost and high performance.  instead of traditional mechanical power switch, it adopts software control power switch.  the basic accuracy of 0.05% and good test stability can compare favourably with those high-end models. being e with
4.3 inch tft lcd display and brand new interface system, th283x series lcr meters possess elegant appearance and easy operation. also, being provided with various interfaces and good compatibility with scpi commands, th283x series lcr meters are convenient for
constituting all kinds of test system and satisfy various kinds of demands for inspection, production and scientific research.
