03/2014 - 4002251801 - AD H250/M40 PROFIBUS R01 en

No ADC TempCal

The device, together with an indication of the error,

must be sent back to the manufacturer for

checking.

No ProcessCal

Activate linearization or carry it out again (HART

communication and linearization software are

required; the original calibration values must be

known), or send the device back to the

manufacturer for linearization.

Indication is supported in cyclic diagnosis only if Ident. Number F201hex is active.
