Test & Measurement

Would you like to add an LCR Meter to your electronics workbench? Build your own! The Elektor 2 MHz LCR Meter Kit is an automatic impedance measuring bridge with extended functionality. Features Measures the resistance, capacitance and inductance of components with an impedance of 10 mΩ to 100 MΩ Test frequency from 50 Hz to 2 MHz Four possible test voltages (0.1, 0.2, 0.5 and 1 Vrms) Additional DC polarization up to 5 V for capacitors and 50 mA for inductors Two configurations possible: Standalone mode with main board + display extension Main board (without display) connected via USB to a computer running the user program (Windows, Linux, MacOS) Specifications Display Parameter valuesEquivalent circuitFrequencyImpedance ∣Z∣Phase ΦQ or DVoltage and current of DUTTest voltage (AC) and polarisation (DC)Range hold statusLabels for multi-function buttons Display size 4.1' (10.5 cm) | 240 x 128 dots Measurement range Parameter Value Inductance L 10 nH - 100 H Capacity C 1 pF - 100 mF Resistance R 10 mΩ - 100 MΩ Q 0 - 5000 for display Phase Φ -90° / +90° Test frequency 50 Hz to 2 MHz in 54 predefined stepsor any frequency within the range Accuracy Up to ± 0.1% ±1 of last digit Total current (MCU board + backlit display board) without polarization420 mA when polarizing DUTup to 650 mA Power supply 5 VDC/1 A USB A (not included)e.g. mobile phone mains charger PC software Windows, Linux, MacOS Dimensions (Hammond case) 6.5 x 4.2 x 2.1' (166 x 106 x 53 mm) Weight 1 kg All the necessary components are included for assembly and calibration: 2 populated PCBs (pushbuttons, rotary switch, and LCD)Note: Before shipping the operation of both assembled boards is carefully checked according to a protocol developed by the original designer Jean-Jacques Aubry. 4 BNC sockets (not assembled) 4 jumpers Hammond case drilled, machined, with printed front and side panels Kelvin cables with clips and 4 plugs Mini-USB / USB-A cable 24-way flat cable (15 cm) Aluminium button for rotary switch Full-color printed assembly manual (32 pages) Adjustment tool for trimmers Required tools Screwdriver, multimeter, and soldering iron.

Elektor Jumpstarter This product is the result of a successful campaign on our electronics project support platform Elektor Jumpstarter. Readers and interested parties can submit their product ideas and, together with the Elektor development team, a finished product can be brought to market after extensive consideration and many tests. Note that these are always small series production runs, so the products are considered 'Elektor Collector Items'.
