About Aideepen ESR Meter GM328B LCD Transistor Tester LCR

Description: LCD GM328B Transistor Tester Diode ESR Meter PWM Square Wave Generator Resistance measurement maximum resolution 0.01Ω, can be measured up to 50MΩ. Can measure a capacitor, capacitance range 25pf~100mF, resolution is 1pF. Capacitance less than 25pF can be measured by parallel connection another known capacitor is greater than or equal to 25pF. Support two diodes to be measured simultaneously and display voltage drop for diode. Automatically test the pins of a component and show on the display. Resistance less than 2100 ohm while it's equivalent inductance measuring range from 0.01mH-20H. Program tape self checking function, Support calibration of multiple parameters. Can be used as frequency meter and frequency generator: frequency range from 1Hz-2MHz and can output 10-bit PWM signal. Notice: Before measuring capacitance, the capacitor must be discharged, otherwise very likely damage the meter. Be sure to disconnect the power from the circuit board when testing the components on the circuit board, the test equipment have residual voltage is not allowed. Parameters: Type: Assembled Tester Display: 1.8inch 160*128 LCD Power Supply: DC 7-12V Current: Approx. 20nA Resistance Measurement: Max. 50MΩ Resistance Resolution: 0.01Ω Capacitance Measurement: 25pF~100mF Capacitance Resolution: 1pF Inductance Measurement: 0.01mH~20H PCB Size: 7.5 * 6cm / 2.95 * 2.36in Product Weight: 50g / 1.79oz Package Included: 1PC * GM328B Transistor Tester 1PC * Case 1PC * Knob
