DANGER: malfunction
If processes are controlled via the signal output,
keep in mind that by pushing the <SP> button the
measurement signal is suppressed and the cor-
responding threshold value is output instead. This
can cause malfunctions.
Push the <SP> button only if you are sure that no
damages can arise from a malfunction.
