After a fault condition occurs, when the
NI.FIU.BoardFault
property is true, you can
identify the specific fault condition by reading the
NI.FIU.BoardFault.*
properties.
Note
Values for fault currents, duration, and temperature limits can be found in the
SLSC-12251 Specifications
and
SLSC-12252 Specifications
.
Measuring the Current
Uncalibrated differential voltage signals that are proportional to the DUT channel's current are
available on the RTI-12306 connector, which allows the signals to be measured by another
device. The external voltage measurement can be used with each channel's stored gain and
offset coefficients to calculate the calibrated current as follows:
I(Amps) =
NI.FIU.CurrentTransducer.Gain
×
V
measured
+
NI.FIU.CurrentTransducer.Offset
where
NI.FIU.CurrentTransducer.Gain
and
NI.FIU.CurrentTransducer.Offset
are properties of Channel_n.
Note
It is important to use the corresponding channel offset and gain for the
current sensors because the values are adjusted to meet the specified accuracy.
Measuring the Temperature
The module's four digital temperature sensors measure the temperature conditions in the
board. For temperature measurement, read the
NI.FIU.TemperatureSensorN
property
where N = 0,1,2,3.
The physical locations of the temperature sensors are as follows:
