VoltLog #6 - Gophert CPS-3205C Calibration
 
06:48
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.

This one is a very short video showing you how to use the drag soldering technique. I am using this method every time I need to solder in line pins, I get good solder joints in half the time it would take me to solder each individual pin. This can add up to a lot of saved time when you’re working on boards with more than 400 solder joints.

Voltlog #34 - Fluke 77 Teardown & Repair, Varistor Replacement
 
13:47
In this video I’m opening the Fluke 77 I scored at a recent auction to show and repair a small issue it has. One of the spark gaps used in the input protection circuit had suffered damage probably while protecting the rest of the circuit when a HV signal was applied to it’s input. For the repair the sparkgap was very hard to find so I replaced it with an MOV. For reference, future Fluke 70 series did switch to MOV protection instead of the sparkgaps so it should be fine and continue to function as intended. The original spark gap part number is Fluke 655134 1500V surge protector.

VoltLog #25 - How to Salvage Electronic Components For Reuse
 
24:37
In this video I am showing various techniques I use for desoldering and recovering electronic components like: inductors, tantalum capacitors, connectors, ceramic capacitors, op-amps, comparators, switches, battery connectors, dc jacks, fuses, mosfets and ferrite beads from old motherboards. I am also taking a look at some laptop optical drivers and lcd panels to see if there is anything useful we can save before taking them to the recycling bin. Here are links to some tools you can use for desoldering jobs: Electric Desoldering Vacuum Gun http://voltlog.com/y/ck5hl Hakko 936 Copy/Fake Soldering Station EU model http://voltlog.com/y/dqj6z Hakko 936 Copy/Fake Soldering Station US model http://voltlog.com/y/l4kbd 15pcs 900M-T Soldering Iron Tip Set for Hakko 936 http://voltlog.com/y/wx7re
