PMU measurement status
ITMs can provide status information for the 4225-PMU measurements in the Analyze sheet Run tab.
The column for the status codes is labeled PMU
x
_
y
_S, where
x
is the PMU instrument number
(PMU1, PMU2, and so on), and
y
is channel number (channel 1 or 2). The PMU status code indicates
pulse measurement status, source and measure ranges, whether an RPM is connected, and load-line
effect compensation (LLEC) status, and flags any faults (errors).
If a pulse measurement fault occurs, the entire row of data related to the measurement is highlighted
in blue (see next figure). A single measurement may have more than one condition. Hover over a cell
to review the status information.
The data values in the flagged data row are color-coded to identify the fault type as follows:
•
Red = Source in compliance
•
Magenta = Measurement overflow
•
Yellow = LLEC failed
•
Blue = Current, voltage, or power threshold reached
