Record Data during a Trial Run of a Railway Car (Train)
With a trial run after the scheduled maintenance of railway cars, check, for example, voltage command signals, motor current, car speed, and brake pressure with a MEMORY HiCORDER.
Simultaneously record both analog and logic over multiple channels.
The car speed can be read directly using a scaling function by inputting wheel rotation detection pulses in the FREQ Unit. Brake pressure is input to the strain unit from a strain gauge pressure transducer installed on the wheel.
In the case of multiple channels, it is effective to capture various command voltage signals with a logic probe.
