Name Data Type Description Semantics
3 Get DC Bias REAL The measured average DC
bias of the transducer
signal in volts. Volts
4 Get Status BOOL Indicates whether a
transducer fault exists
(the measured DC Bias is
outside the range
specified by Fault High
and Low). 0 = No fault
1 = A transducer fault exists
7 Get/Set Fault High REAL The maximum expected
DC Bias voltage from the
transducer in volts. Volts
8 Get/Set Fault Low REAL The minimum expected
DC Bias voltage from the
transducer in volts. Volts
9 Get/Set Power Type USINT Indicates the type of
power supplied to the
transducer. 0 = No power supplied
3 = Bias current for passive
magnetic sensors
13 Get/Set DC Bias Time
Constant REAL The time constant value
used for exponential
averaging of the DC Bias
value (a low pass
filter/output smoothing
filter). Seconds
