Fully auto-ranging designed High resolution, up to 5 digit display, most resolution: 0.01pF, 0.001uH High stability and measurement range for L/ C LCD display with backlight USB PC program, can take record and pass and fail component sorting function. Capacitor discharge terminal and capacitor storage voltage display. MLC500 LC meter is auto-ranging component tester, can drive up to 500 KHz, suitable for small value capacitor and inductor measurement. It provides very stable and high resolution measurement up to 5 digits. Meter can measure 0.00pF to 100.00mF capacitance and 0.000uH to 100.00H This meter is using two technique measurement, LC oscillation and RC oscillation. LC is much suitable for small value measurement and RC for capacitance. Discharge Capacitor before Testing!! Please 't connect under testing device during power on, it will affect the initialization. Inductor Measurement: Test lead plug to black and red (right side) socket. Press Mode/Range button to select inductor mode Capacitor Measurement: Test lead plug to black and red (right side) socket, capacitor with polarity please follow the - and + sign. Press Mode/Range button to select capacitor mode USB External Power: USB 5V, you can use standard 500mA USB charger or PC port for external power, suggest to power off before plug in or remove USB cable Discharge: Display the current capacitor's voltage; please discharge the capacitor 1 V before you put it to measuring terminal. Frequency: Display the current measurement frequency, frequency is not tunable by user, and it change automatically according the under testing component Colour:Black Material:plastic Package Contents: 1 * Digital Capacitance Inductance Meter Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
