Hi everyone,

I have a Shimadzu SIL-20A Prominence autosampler and the other day I received the error "NO PUMP ADJUSTED". According to the manual this is a possible malfunction with the measuring pump. I contacted a Shimadzu engineer and he suggested I do an LPV adjust. Problem is...this is considered a fatal error and the error message can't be cleared, so I can't get into the autosampler menu to try what he suggested. Does anyone know how to clear this type of error message? I've tried asking the engineer and a few others but no one is replying to me. :( I'd at least like to try to fix this on my own by doing what he suggested before requesting an actual service call. There has to be a way to clear it!
