Feature: 1. The AT2811 is a general-purpose LCR digital bridge with a high-performance microprocessor-controlled micro-desktop instrument. 2. The main parameter 0.8 inch large character highlight digital tube display, supports the comparator function and supports the open circuit clear function of the full range short circuit. 3. 0.25% basic accuracy, maximum 33000 digits display digits, support for six-range automatic or manual testing. 4. Enhanced impact protection, more convenient and practical to use. 5. The instrument can automatically measure inductance L, capacitance C, resistance value R, complex impedance Z, quality factor Q, dissipation factor D. 6. Easy-to-operate operation interface, built-in sorting function, 5 levels sorting display and sorting alarm setting. 7. It can easily meet the requirements of accurate testing and mass production of various component manufacturers, schools, research institutes and metrological quality inspection departments. 8. The four levels test frequency is 100Hz-10kHz, and 30Ω and 100Ω source internal resistances.
