Hello,
I am trying to get an old Mettler (DL38) up and running and am having trouble getting it to blank (pre-titrate). Once it does blank and states "ready" it drifts back so quickly that I am unable to even determine an adequate concentration for my Comp5 or get an accurate standard reading. Anyone out there still using a DL38? Or can anyone help me with this issue. I know I've got vacuum on the sysytem because I don't have any trouble filling or emptying.......
