Transducer Test - HBM MP85A Operating Manual

MP85A process controller
This means that, following an immediate start of a new measurement, the
result and curve files will not be immediately transmitted. So you should only
choose this method if very fast processes have to be monitored and the
results and curves are merely used for spot checks.

8.3 Transducer test

The transducer test can be triggered via the digital input or via the bus signal.
At low filter limit frequencies, the filter settling time must be waited before the
test. A pulse of minimum 5 ms duration at the digital input is necessary for the
transducer test. The result is typically available another 10 ms later.
