hi,

When on Position #1 , all the switch wipers are connected to Pos#1
Remember it is the switch wiper which is making the selection for each individual group

When the mode is on position 1,do all the contacts(circles)that have the upper 1 numbers are connected?
No, all the Pos#1 circles are not linked together
Even though the wiper is connected to position #1, unless there is a wire connected to pin #1 of that group, the wiper goes to no other part of the circuit, it is open circuit.

When the selector mode on position 2,do all the contacts that have the upper 2 numbers are connected?
No,

When the selector mode is on position 3,do all the contacts(circles)that have the upper 3 numbers are connected?
No,

When the selector mode on position 9,do all the contacts that have the upper 9 numbers are connected?etc...etc..etc...
No,
There is no need to attribute the question specifically to this scheme,
but to any scheme that uses this pattern of numbers with selector switch.

Hi,
So,from your explanation,i understand that it is not possible to know,by the scheme, which contacts the selector switch,actually,come in contact on each position and i have to practically dismantle the dmm and check it.
Am i right?

 

hi xch,
I am not saying it is not possible to work out the switch wiring of a scheme when using the Annotation: Switch Position/Bank.
Look at this image for a simple explanation of Annotation method.

EDIT:
Added a second image as a test.
Can you work out on which switch positions, the Input is connected to the OutpuT.??

Hi Eric.
Thanks for the attached images.
I understood,more or less,the role of the switch banks and their position,but i failed
to answer your test question.I didn't undersand how to solve your question by the image.

hi,
I am surprised you cannot solve that simple problem.
Find which wired switch position numbers are COMMON to all Banks.

Hi.
Position 6,7 and 10?
Was that what i had to look for?

 

hi,
Yes that is it.
Use the same method on your DMM switch project.
Make a drawing of each section of the DMM's switches so that it is easier to follow.

Thanks,Aric,for your help and for your patience.
