Corrective maintenance starts when an instrument has already failed or the results can no longer be used. Mahut diagnoses the fault and restores the system.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t

A photo of the error text, the last good run, and the instrument model saves time. If a part is already suspected, say so, but do not leave fittings open or columns drying out while you wait.<\/p>
If the same fault returns every month, ask for a preventive maintenance program<\/a> after the instrument is back in service.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
