Performance characteristics and functional applications of AT2811LCR digital bridge

AT2811 is a universal LCR digital bridge, a miniature desktop instrument controlled by a high-performance microprocessor. Four levels of test frequency are 100Hz~10kHz, 0.1V, 0.3V and 1V levels are optional, and 30Ω and 100Ω internal source resistance are optional. The instrument can automatically measure inductance L, capacitance C, resistance R, complex impedance Z, quality factor Q, and loss tangent D. The newly designed AT2811 has the highest cost performance and a fool-like operation interface, which can easily meet the requirements of various component manufacturers, schools, research institutes and metrology and quality inspection departments for accurate testing and mass production. The instrument has a built-in sorting function, with five levels of sorting display and sorting beep settings.

Performance characteristics

● 0.8-inch LED display for main parameters and 0.5-inch LED display for secondary parameters can display primary and secondary parameters at the same time, with 5 display digits each.

● Display A: L, C, R, Z

● Display B: Q, D

● Full frequency short circuit and open circuit clearing

● Comparator (sorting) function:

● 5-level sorting results: 3 percentage-qualified files, 1 auxiliary file, and 1 unqualified file

● Comparator function display: directly using LED signs to display

● Beep: You can set the beep switch for all comparator results.
