Hach sc1000 User Manual

76
Standard Operations
A set of functions is available to set the error and warning status of output modules. Each
of these functions requires a minimum of 2 (or 3) parameters and allows a maximum of
32 parameters. In calculations all functions take the value of first argument A as the
function result, so the use of these functions does not affect the calculated value.
Table 26 Check functions to set errors and warnings
