I have an IL 943 which will not set zero. It sets the 140/5 properly but the NA only goes as low as about 30. The aspiration rate is correct and the voltages on the preamp are also correct. I've aslo ran it in the predilute mode eliminating anything to do with the dilutor or mixing cup. Any suggestions?
