Measurement Setup- Trace
With the trace mode, the user can measure up to 16 order traces plus 4 overall
traces over a start-up or coast down process. The order traces contains both
magnitude and phase data, so the user may display the order traces in various
formats, like linear, dB, phase, polar plot, etc.
The Measurement Setup is very important to understand so that you can make
correct measurements. The Fieldpaq
tm
gives the user the ability to quickly modify
the measurement setup to account for in-field conditions, making the Fieldpaq
tm
a
very valuable instrument that is adaptable to a wide variety of measurement
requirements.
RPM:
Start RPM, Stop RPM, Delta RPM
Start RPM
: via the
[Navigation Keypad]
press
[OK]
and then enter the desired starting
RPM. This can be between 6 and 480,000
rpm.
The order trace measurement is armed
by the rotation speed. The Start RPM
defines the target speed, at which the
measurement starts.
Stop RPM:
via the
[Navigation Keypad]
press
[OK]
and then enter the desired starting
RPM. This can be between 6 and 480,000
rpm. The Stop RPM defines the target speed,
at which the measurement stops.
Delta RPM:
via the
[Navigation Keypad]
press
[OK]
and then enter the desired
delta RPM. This can be between 0.1 and 480,000 rpm. . The Delta RPM
defines the step size between two measurements. However, to capture data as
much as possible, the order tracking program allows a margin for the Delta RPM,
that is, any rotation speed that falls into the range of ±50 % of the delta RPM will
