In this video I am calibrating the Gophert CPS-3205C power supply using my Keithley 175 4.5 digit multimeter and my adjustable dummy load. If you haven't watched the review click here: https://www.youtube.com/watch?v=t49P2nh9_t0 Purchase CPS-3205C: Banggood: http://voltlog.com/y/ydbz8 Ebay: http://voltlog.com/y/qfiwh Amazon: http://voltlog.com/y/r4zhk Aliexpress: http://voltlog.com/y/p2hv9 The calibration procedure is: 1. Set the V/A selector switch to A position, 2. Push the adjust knob then power on the power supply,the meter will display PUSH OFF, 3. Press the ON/OFF button one time then press the LOCK button two times, the unit will go into voltage calibration (please note calibrate the voltage with no load), the voltmeter displays 01.00 and amp meter displays 001. 4. please adjust the adjust knob to set the output voltage to 1.005V,( you can push the adjust knob to select the range of adjusting) then press the ON/OFF button to calibrate the output voltage to 10.00V and 30.00V, after 30V voltage has been calibrated, please press the ON/OFF button to go into current calibration, connect your electronic load to the output terminal of the power supply, the unit must operate in C.C mode,the amp meter displays 1.00 and the voltmeter displays 0001, please adjust the adjust knob to set the output constant current to 1.000A, then press the ON/OFF button to calibrate the output constant current 5.000A,after 5.0A has been calibrated then press the ON/OFF button to finish the calibration. ... https://www.youtube.com/watch?v=5qB0GPkt2KM

After replacing the battery in this iphone 5c, the phone kept rebooting itself without any apparent reason. By using a schematic and board view of the logic board I was able to find the fault and repair it.

In the previous video, I reviewed the UNI-T UT8805E multimeter, but it was jam-packed with info! So, I decided to dedicate a whole video to cracking this bad boy open. Let's see what makes this professional-grade multimeter tick! We're about to embark on a teardown adventure, dissecting the UT8805E to reveal its high-quality components and construction. From top-tier Analog Devices op-amps to a powerful TRION FPGA, I'm gonna show you the heart of this impressive instrument. Remember those potential issues I mentioned in the review? Well, UNI-T assured me they've been fixed in a newer revision. They're sending one over, so stay tuned for a follow-up video where we put the new unit to the test! →Buy The UT8805E EU Eleshop https://voltlog.com/y/70kmq US Amazon https://voltlog.com/y/6cjt8 →UNI-T UT8805E Official Website https://voltlog.com/y/vpljb →UT8805E User Manual https://voltlog.com/y/09g8u →UT8805E Datasheet https://voltlog.com/y/6zq2s →UT8805E Programming Manual https://voltlog.com/y/fhrtm →LXI Tools Project Github https://voltlog.com/y/8jrn1 In this teardown, you'll get a front-row seat to: A meticulous breakdown of the UT8805E's internal components. A deep dive into key ICs like the STM32F407 processor and the AD7122 ADC. My take on the component quality, assembly, and any potential areas for improvement. A comparison to other high-end instruments on the market (mention specific brands if applicable). Hit me up in the comments and let me know what you think! Are you as impressed as I am with the UT8805E's build quality? What features are dealbreakers for you when choosing a multimeter? Have you had any experiences with other high-end multimeters?
