Always adhere to hazard warnings and safety tips when using reagents, chemicals and cleaning agents. Please adhere to the respective safety data sheet! Download the safety data sheets for the supplied reagents at www.lenntech.com Intended use ® Testomat ECO C is used for the automatic determination and moni- toring of carbonate hardness in water.
Pay particular attention to Warning notices in these instructions The warning notices in these instructions warn the user about poten- tial dangers to individuals and property resulting from incorrect han- dling of the instrument. The warning notices are structured as follows: Description of the type or source of error Description of the consequences resulting from non-obervance SIGNAL WORD!
Pay particular attention to If the measuring water contains more than 20 mg/I CO (carbonic acid), erroneous evaluations cannot be excluded (if necessary, use aerator type R). The concentration of influencing contents can be determined by ® using our colourimetric TESTOVAL test kit.
Pay particular attention to Cleaning Only use a dry, lint-free cloth for cleaning. De-installation Prior to de-installing a defective instrument, always write down a description of the error (failure effect). It is only possible to repair a defective instrument (irrespective of the warranty period) if it has been de-installed and returned to us with a description of the error.

An analysis is always triggered with higher priority when the programmed interval time has been reached. Selecting the function TIME-CONTROLLED ...
Entering basic program data Limit value monitoring It is possible to program the limit values on a continuous scale. The Monitoring of two limit value range depends on the used indicator type and the pro- limit values grammed unit. For the duration and duration/inverse switch functions, limit 1 is the upper limit and limit 2 is the lower limit.
