6.5 Integral Indicator and Error Display
For temperature transmitters equipped with an integral indicator, errors in the temperature sensor or the
transmitter cause an integral indicator to call up the applicable error code. Table 6.5 lists the error codes for
HART and BRAIN. Table 6.7 lists the error codes for Foundation eldbus.
