Hi Amarbir, I used to love and have the same opinion. Now, my opinion has changed. I bought mine from Tequipment.

After 10 month, I started having problems with the meter. I called Tequipment and they sent me a new 608 and told me to scrap the old meter. After 6 month of using the second 608, I started having problems with measuring high value resistors. That is when my opinion changed.

Protek 608 manual I scanned in the original manual into a PDF ( Dropbox link ). This is a more convenient referencing on my PC when developing software for the multimeter.

I called Tequipment and they offered to send me a third 608 meter. I refused and instead asked for a Amprobe 140. I got credit and paid the difference. Hi Amarbir, I used to love and have the same opinion. Now, my opinion has changed.

I got credit and paid the difference. Hi Amarbir, The first unit had problems with turning off the APO.

I could not get it to work. Also, the meter would lock up for some reason. The second unit high resistance would not measure correctly. I was trying to measure 10 megohms. I was getting lower ohms readings than 10 meg.

I took the unit apart and tried to clean the PCB thinking that maybe some flux was on the PCB. Another thing that I might add is that maybe I was unfortunate to have gotten two meter from a bad batch. The serial numbers on both meter were one one apart. Apparently, both were manufactured on the same production line and followed each other. Maybe that is why both unit failed. You won't find Zener testing because of the voltage that would be required at the probes. Suppose you want to test Zeners up to 30V, there would have to be 30V across the probes, and the meter would have to be able to source enough current to put the Zener into its constant voltage region.

That's enough to cause damage to other components, and nobody wants a meter that damages the circuit they're probing. For small Zener voltages, the regular diode test function will work just fine. If you have, say, a 3.3V Zener, the diode test function will report 3.3V with the probes one way round and about 0.6V with them the other way round. To test higher Zener voltages, you need a power supply, a resistor and a voltmeter, that's all.

Funny thing -- it turns out that the Protek site has a P3502C service manual! It's the same scope as the P3502 except for one added feature for component testing. I bet this manual is just what you're looking for.

Can't get a clear picture? You mean you can't focus the beam with the focus knob? If I had to guess. There are some service adjustments for focus covered in the manual I think. Also could be a problem with the focus circuitry. Could be a tube problem. Download da serie the vampire diaries 3 temporada legendado. Not sure what you mean by being unable to 'get things to move around ground?'

Let me know if I can help. I am starting to get a better handle on how these things work so maybe I can steer you in the right direction. Meanwhile here is a great troubleshooting guide that applies to all scopes even tho it is written by/for Tek. I couldn't make out the settings but that is ok. Interesting behavior!! Take a look at that PDF and just kind of skim through it and get the gist.

Their approach is--diagnose from the front panel. That's what we'll try and do. So, step one, diagnose the faulty section. The o-scope is made up of several main sections. The power supply of course provides various voltage to all the other sections. The vertical section controls the position of the beam on the vertical axis. At present I'd put my money on a problem with the vertical section.
