A wire break check is carried out (i.e. test cur-
rent flows).
Undefined No "wire break" diagnostics is reported.
No wire break check is carried out (i.e. no test
current flows). This is required to calibrate
thermocouples, since the test current neces-
sary for a wire break check leads to measure-
ment errors during calibration.
