Respected all,
I have Aloka SSD-500 Machine having system version 5.
near gain is not giving very prominent contast result on B-Mode Image, but that is acceptable, but not ideal..
The real problem is that when we decrease the far gain using the STC variable resistor placed above the main gain knobe, as soon as the far gain decreased below 1.0, we get error on screen"Inv. Probe" (Invalid Probe) and B-Mode disappears.
Where could be the issue? How to resolve the issue? Any help will be highly appreciated.
Best Regards,
Mehran Ashraf
