– Allowed error: enables the specification of the permissible error between two channels
in a range from 0.1 .... 100.0 [...]. The error must not be greater than 10% of the defined
measuring range (e.g., 4 ... 20 mA --> 16 mA * 0.1 = 1.6 mA).
– Error tolerance time (0.1 ... 2.5 s): maximum permissible duration in the event that the
specified error (“Allowed error”) is exceeded.
