Product Description



  • Simultaneously display of four different parameters with flexible combinations
  • AC and DC parameters can be measured simultaneously without interference; self-demagnetization
  • High speed and efficiency measurement: Max. 65 meas / sec (with display)
  • Built-in bias voltage: -5V- + 5V; resolution: 1mV
  • Support DC source output: continuously adjustable independent voltage source -10V ~ 10V, resolution of 2.5mV, low noise
  • Auto DUT trigger function: the DUT can be measured once be trigger and the measurement results and discrimination will be displayed.
  • Flexible limit comparator: support tolerance mode, sequence mode and parameter exchange
  • Rapid and easy determination of Pass/Fail through multi-parameter test function 
  • Powerful list sweep function: mixed scanning of various excitation source and display of different parameters; also support multiple-channel scanners of devices
  • New graphical scanning functions: frequency / level / bias / DC source make nuanced analysis of elements
  • Complete user correction function: up to 32 dot frequency correction; can be applied to multi-channel scanning amendment for higher measurement consistency and repeatability
  • Rich communication interfaces: RS232C / USB-CDC / USB-TMC / HANDLER / GPIB
  • Multiple USB storage modes: CSV and TXT format for storing test data, BMP, PNG, GIF formats for stored on-screen images, U disk storage / recall setup files, U disk firmware upgrade
  • Storage / recall of Parameters: real-time storage of all parameters without losing after shutdown; supporting internal storage of 100 groups, external storage and recalling of 500 groups


Brief Introduction

U2816 Series Precision LCR Meter is a new generation of impedance test equipment with high accuracy, wide measurement range and six digits resolution. Being possessed with test frequency up to 200kHz, testvoltage of 10mV-2V, built-in typical DC bias and -10V-10VDC voltage source output, it can meet all requirements for measuring components and materials and provide guarantees for production line quality assurance, incoming inspection and laboratory precision measurements. Otherwise, the Handler, RS232C and GPIB interfaces as well as improved command system provided by the instrument make it easier to build the test system.
