_PCS4•TEST•SOLENOIDS?
Performs a functional test of the internal pressure
control valves.
Response:‘T stat, stat, stat, stat, stat<,stat> cr lf’
Where stat = PASS or FAIL.
If six solenoids are installed, a sixth stat is re-
turned.
_PCS4•TEST•SOURCEP?
Determines the source pressure applied on the
Supply port of the instrument. (Used to determine
the approximate maximum control pressure.)
Response: ‘T value cr lf ’
Where value equals the approximate source pres-
sure up to a maximum of 110% of the primary
transducer range and units identifies the units of
measure.
_PCS4•TEST•XDUCER?<•digits>
Functionally verifies main internal transducer un-
less other transducer is specified by digits. Tests
for nominal values, not for accuracy.
Response: ‘T stat, digits, digits cr lf ’
Where stat is PASS or FAIL (the result of the RAM
test and digits are the pressure counts and digits
are the temperature counts. If no transducer is
specified, the main transducer (0) is tested. If a
non-existent transducer is specified, the test will
be performed, but will fail with unusable counts
returned.
