M181 LCR meter is a practical kit for measuring the R, C, or L of either through-hole or surface-mount components. It features about 1% accuracy, which is adequate in most engineering scenarios. Not only being very easy to build, it also includes a Self Test mode that helps users to verify the correctness of assembly. Compact in size and the capability of serial output make the meter a great choice for many embedded applications. Built-in virtual USB comport for data output and firmware upgrade Serial data output via USB comport or direct LVTTL Highlights of M181 LCR Meter: Resistance range: 0.1ohm - 10M ohm Capacitance range: 1pF - 10000uF Inductance range: 1uH - 20H Fully automatic ranging Accuracy: about 1% Measurement frequency: 1KHz/100Hz selectable Measurement voltage: 0.6Vpp Display HOLD function USB (5V) powered Easy to build, easy to use Self test mode for verifying the correctnes of assembly Acrylic panels included Specifications: Display: Primary: R, C, L Secondary: Q, D, ESR Equivalent Circuit Mode: Parallel or Serial Measurement Range and Accuracy: R, |Z|: 0.1Ω - 10MΩ C: 1pF - 10000μF L: 1μH - 20H Q, D: 0 - 10000 Accuracy: About 1% Measurement Conditions: Test Frequency: 100Hz, 1KHz Open Voltage: 0.6Vpp Miscellaneous: Measurement Connections: 4 Kelvin wires on the test terminals Ranging: Fully automatic Compensations: Open, Short Serial Data Output: Yes Power Supply: USB Power Consumption:Less than 100mA @ 5V Dimensions:66 x 32x 19mm (2.60x1.26x0.75Inch) Weight:23g (76g with probes) Note: Due to different production batches, accessories may have random differences, which cannot be specified and will not affect use. It's DIY kits, needs to finish by yourself. Colour: parent Material:ABS Package Contents: 1 set * LCR
