#Protek 506 service manual manualIgazából az a kérdés: van-e valamilyen univerzálisan használható L-C áramkör, vagy kreálni kéne valamilyen sávszűrőt hozzá? Ha működhet univerzális megoldás, akkor szívesen fogadnék kapcsolásokat, értékeket. View and Download Kenwood RXD-V525 service manual online. True RMS AC voltage.Operating Temperature: 0. Azt azért tudom, hogy ezt jó nagy puffer kondival nem fogom kisimítani. Product Description Dual display for frequency,AC voltage and Temperature measurements 10 MHz frequency counter and decibel measurement. ![]() Tanácsot kérek, hogyan lehetne kisimítani a tápot. :redsad: Feltételezem, a DC-DC konverter működéséből adódóan zajos a kimenete. Protek 506 True RMS multimeter with leads - 100 Georgetown. DC Voltage : 0 - 400mV/4V/40V/400V/1000V. I have its service manual printed and one probe somewhere I can not find right now. #Protek 506 service manual PcJelentem működik! :taps2: Viszont durván zajos lett a szkóp jelképe. Complete with carrying case, instruction manual, test leads, battery, RS-232C PC Interface cable and software. Átalakítottam, mégpedig úgy, hogy átvágtam a stabil kockák kimeneti lábait, és bekötöttem a DC-DC konverter kimeneteit (a két +5V-os ág párhuzamosítva). Ezt találtam: MEAN WELL DKE15A-05 Ez az átalakító +/-5V-ot állít elő áganként 1,5A-es terhelhetőséggel. I installed them,then powered up,it started arcing on D1012 and D1022 and all the ISS83 equivalents failed except for D1022? I ordered some UF4007s and installed them but I used a dim bulb tester this time with a 40 watt bulb installed and sure enough it lit up? So its shorting out /dragging current somewhere? So I disconnected 2SD880(TR1005)Thinking that must be where its coming from But the bulb lit again at power on, with a 75 watt bulb in the DBT? All the components seem to read OK on my DMM? Ive built a high voltage tester kit to try and figure out whats going on with this thing? Should I remove just the diodes and power it on to measure the high voltage rail, or is there a chance of blowing up anything else? Ive uploaded a schematic showing the diodes that failed,the 10mega ohm resistor(R1024) read shorted when I measured it in circuit but when I removed the shorted diodes it read OK?Įdited by Scott Wang : You attached too many circuits, so I deleted the rest, maybe you should check the switch of your mouse, mine also have that kind of problem.Tiszteletem! Az alább linkelt topikban már volt szó erről a szkópról: Ott felmerült, hogy ki lehetne váltani a belső +/-5V-os tápot a melegedés miatt külső egységre.

I'm waiting for a high voltage measuring kit to arrive in the post so I can do that. Guideelse pro tools 8 user manualelse radiant bruciatori rmas24e installation manual service manual user guideelse. The thing I would like to know is what could have caused these diodes to fail? I don't want to replace these diodes only to have them fail again? My knowledge of circuit theory isn't up to scratch by a long way? So I thought the best place to ask this is at the AAC circuit gurus hang-out? I bought the scope through the Trading Post online,when it arrived it had a broken plastic voltage adjuster for 230v,120v,100v etc. I found 3, ISS83 diodes had failed in the circuit so I ordered 3 Ultrafast UF4004 diodes by post because I couldn't get the ISS83s? The UF4004s are twice as fast and have the same capacitance according to the datasheets. ![]() I have a Huang Chang: Protek 6502 20mhz oscilloscope that has developed arcing across D1012 in the power supply next to the fly-back transformer. ![]()
