+Vs needs 7.5V, -Vs needs -2.5V, GND is ground, VDD needs 4.75/5V

my question is where to the wires go into the power supply which configuration.

Thanks

 

What is that instrument? Show us the full front panel.
You need a power supply to provide the three voltages specified.

 

yeah its a triple output DC power supply

 

got it working, phew!!

 

Assuming that the +25V and -25V suppies are independent, connect the two BLACK and one GREEN terminals together.

Use the +6V supply adjusted for +5V.

Adjust the +25V supply for 7.5V.

Adjust the -25V supply for -2.5V.

 

yeah thats what i did,only i put wire from GND into the COM port, results are as i wanted

Be aware that the Green post is connected to the building's earth (electrical panel) ground through the third prong of the power supply's AC Line cord.

You may or may not want to connect the circuit you are testing to the building's earth ground.
