FEATURE DESCRIPTION
Tolerance Type
(required drop
down list
selection)
Selects the DUT tolerance formula used to calculate DUT error at test
points. Choices are:
%DUTFS
DUT tolerance is calculated as the pressure span of the
DUT times the tolerance value. Span and full scale errors
are always the same when the DUT
<Minimum
Pressure>
value is zero.
%Reading
DUT tolerance is calculated as the current reading of the
DUT times the tolerance value.
%DUTFS or %DUTreading (greater of)
DUT tolerance is calculated at
each point as both %DUTFS and %reading. The tolerance
used is the greater of the two.
%DUTFS + %reading
DUT tolerance is calculated at each point as both
%DUTFS and %Reading. Tolerance used is the sum of
the two.
Pressure Unit
DUT tolerance is specified as the
±
value of the fixed
pressure value entered in the DUT pressure range unit
(from the DUT Definition
[Range]
tab).
Output Unit
DUT tolerance is specified as the
±
value of the fixed
output value entered in the DUT output range unit (from
the DUT Definition
<Range>
tab).
None
There is no DUT tolerance specification.
Tolerance Value
(required numeric
entry field)
Specifies the numeric value used to calculate the DUT tolerance.
Combination tolerance selections provide two entry fields.
6.8.2.5 [READ] TAB
The DUT Definition
[Read]
tab defines how FPG Tools acquires data from the
DUT. Whatever the data acquisition method, DUT pressure output data must be
obtained in the output units specified on the
[Range]
tab. DUT’s that interface
directly by RS232 or IEEE-488 require a remote command setup. Manual DUT
data acquisition selections require a DUT output entry for each point taken.
Table 39 provides information on the individual

tab fields.
