The auto off feature on the Lovibond PM600 cannot be reset manually. It switches off automatically after 20 minutes of inactivity. To prevent this, press any key within 30 seconds of the warning beep or ensure the instrument is active (e.g., during countdown or printing), as the auto off is inactive while working.

Page 9 1.1 Methods The precision of Lovibond® Reagent Systems (tablets, powder packs and tube tests) is identical to the precision specified in standards literature such as American Standards (AWWA), ISO etc. Most of the data referred to in these standard methods relates to Standard Solutions. Therefore they are not readily applicable to drinking-, boiler- or waste-water, since various interferences can have a major influence on the accuracy of the method.
