Hi there,
I need to isolate if my programmer is faulty.
Below are the multimeter voltage readings so I will appreciate if someone could give me a light to determine if I need to replace it.

HW: 239v...
Thanks
I have followed your instructions, the results with the multimeter are as follows: (please see the attachment diagram for numbers)
When both CH and HW are "off"
