5.5 QUERY
FUNCTIONS
The following are 'query only' functions sent to the UPC through the communication bus.
5.5.1 CONFIGURATION QUERIES
These query parameters are set via DIP switches within the UPC, not via bus communication. The
values are specific to the hardware configuration of the individual power source.
:[SOURce]:XFMRRATIO?
Query: Output XFMR ratio.
Returns <0.01> to <5.11>. See para. 3.4.1
:[SOURce]:AVR?
Query: Current transformer AMPS:VOLTS ratio.
Returns <1> to <511>. See para. 3.4.2
:[SOURce]:CTLOC?
Query: Current transformer location.
Returns <1> (PRIMARY) or <0> (SECONDARY). See para. 3.4.4
:[SOURce]:AMPLIFIERS?
Query: Number of installed power amplifiers in Power Source.
See para. 3.4.4
:SENSe:CURRent:RANGe?
Query: AMPS meter range.
Returns <0> to <AMPS meter range> RMS Amps
5.5.2 METERED DATA QUERIES
Measurement occurs once per :MEASure: command. AC measurements are assumed.
•
The
SCPI
:AC
keyword following
:MEASure
is optional and is not shown here.
•
The
“
?
” is optional as
:MEASure:
implies a query. Values following a command are ignored.
•
'Multiple keyword' queries may be performed to obtain values of simultaneous measurements.
e.g.,
:MEASure:VOLTage1;VOLTage2;VOLTage3?
:MEASure:VOLTage1?
Query: metered voltage
Φ
A.
Returns <0> to <354> VAC RMS
:MEASure:VOLTage2?
Query: metered voltage
Φ
B.
Returns <0> to <354> VAC RMS
:MEASure:VOLTage3?
Query: metered voltage
Φ
C.
Returns <0> to <354> VAC RMS
:MEASure:VLL1?
Query: metered Line to Line voltage
Φ
A to
Φ
B.
Returns <0> to <354> VAC RMS
:MEASure:VLL2?
Query: metered Line to Line voltage
Φ
B to
Φ
C.
Returns <0> to <354> VAC RMS
:MEASure:VLL3?
Query: metered Line to Line voltage
Φ
C to
Φ
A.
Returns <0> to <354> VAC RMS
