UNI-T UT603 LCR Digital Multi-Meter Review - Inductance, Capacitance, Resistance, Transistor hFE,
UNI-T UT603 is a mid-range LCR Digital multi-meter. It can measures capacitance, diode/continuity, inductance, resistance, transistor hFE. Not so bad LCR multimeter and it's just nice for beginners out there to measure electronic component especially ceramic capacitors capacitance, inductance, and the transistor hFE value. You can salvage a lot of electronic component and use this multimeter to measure their specific ratings before they can be of any used. Without digital multimeter working in electronic is far much slower due to unnecessary wasting time research especially the value of the electronic components specification.
One simple circuit to step up voltage using LM2577 -Adj P+ chip. The schematic is from Texas Instrument and it works expected - and below is...
