HBM MP85A - Transducer Test

Communication with a control system
MP85A A0293_06_E00_03 HBM: public 95
Time until stop (follow-up time, only possible when using
internal stop condition)
Ready
Running
Result valid
Process OK
Save to MMC/PC
Save (to RAM)
Offline evaluation
Measurement
Initialization (typ. 25 ms)
Reaction time (typ. 2 ms for external signal)
Started
Stop (condition fulfilled) or end, if ext. signal for end
condition is used and signal “End” is active
Start (ext. signal “Start”
or condition fulfilled)
Signal is only set if end
conditions are fulfilled and
data is saved to RAM
(internal) end condition fulfilled
(with ext. signal ”End” this is
already fulfilled)
Fig. 10.2 Process-optimized procedure
This means that result and curve files may not have been transferred if a new
measurement is started immediately. You should therefore only choose this
method if very fast processes have to be monitored and the results and curves
are merely used for random spot checks.
10.3 Transducer test
Initiate the transducer test via a digital input or a bus signal. At low filter limit
frequencies, you have to wait until the filter settling time has elapsed before the
test. A pulse of at least 5ms duration at the digital input is required for the
transducer test. The result is typically available another 10 ms later.
