the tech next to me uses the simpson 260 to test for OPEN components or if vcc and ground is open. he said that it takes a lot of current to drive the simspon needle to read an open compared to a digital meter will not read overload when there is an open circuit or component. is this true? that a digital meter will measure random when there an open
I am just trying to follow all this, as i am sure you will appreciate it is all somewhat complicated. So let me see if i have things correct so far, lets call this a recap.
In your company when you have a dead/dud board, it goes to a as yet unnamed department.
On its arrival to said unnamed department, the board is given to the ' MANAGER ', who obviously being the manager, and in charge is allowed to
play with use the oscilloscope.
He presumably is the slightly more technical one, as he is the one that answer's some of your questions, and on occasion has a good idea. So he....
randomly pokes about probes the board.
Now this bit i am unsure of due to recent information you have given, but here goes, lets see if this is right. After his
random poking about probing of the board, he declares the fault as either a short, in which case he passes it to you, presumably because he know's you have no chance of finding the short, seeing as you ask him so many basics, such as how to switch the meter on. Then after a unknown and again presumably random time frame, declares that you desolder a large amount of unknown IC's, in the hope that will scare the short away.
or he declares the fault as open, and obviously as this is a different type of fault, to the one you are designated to find, he passes it to a recently discovered other, who is designated the open fault finder?
do i have this correct so far?
