5.13 MEASure Group

The commands in this group deal with computation.
You can make the same settings and queries that you can on the screen that appears by using Setup menu >
Computation/Output tab > Efficiency button, the screen that appears by using the Δ Measure button, the screen
that appears by using the Update Rate/Averaging button, and the screen that appears by using the Measure button.
:MEASure?
Function Queries all computation settings.
:MEASure?
Syntax
:MEASure:AVERaging?
Function Queries all averaging settings.
Syntax :MEASure:AVERaging?
:MEASure:AVERaging:COUNt
Function Sets or queries the averaging coefficient.
:MEASure:AVERaging:COUNt {<NRf>}
Syntax
:MEASure:AVERaging:COUNt?
<NRf> = 2 to 64 (attenuation constant when
TYPE = EXPonent)
<NRf> = 8 to 64 (moving average count when
TYPE = LINear)
:MEASURE:AVERAGING:COUNT 2
Example
:MEASURE:AVERAGING:COUNT?
-> :MEASURE:AVERAGING:COUNT 2
Description The averaging of harmonic measurement
functions is only valid when TYPE is set to
EXPonent (attenuation constant). For details, see
the features guide, IM WT5000-01EN.
:MEASure:AVERaging[:STATe]
Function Sets or queries the on/off status of averaging.
Syntax :MEASure:AVERaging[:STATe] {<Boolean>}
:MEASure:AVERaging:STATe?
:MEASURE:AVERAGING:STATE ON
Example
:MEASURE:AVERAGING:STATE?
-> :MEASURE:AVERAGING:STATE 1
:MEASure:AVERaging:TYPE
Function Sets or queries the averaging type.
:MEASure:AVERaging:TYPE {EXPonent|
Syntax
LINear}
:MEASure:AVERaging:TYPE?
:MEASURE:AVERAGING:TYPE EXPONENT
Example
:MEASURE:AVERAGING:TYPE?
-> :MEASURE:AVERAGING:TYPE EXPONENT
Description The averaging of harmonic measurement
functions is only valid when the type is set to
EXPonent. For details, see the features guide, IM
WT5000-01EN.
IM WT5000-17EN
:MEASure:DMeasure?
Function Queries all delta computation settings.
:MEASure:DMeasure?
Syntax
:MEASure:DMeasure:MODE
Function Sets or queries the voltage or current mode that
is used in delta computation.
Syntax :MEASure:DMeasure:MODE {RMS|MEAN|
DC|RMEAN|AC}
:MEASure:DMeasure:MODE?
:MEASURE:DMEASURE:MODE RMS
Example
:MEASURE:DMEASURE:MODE?
-> :MEASURE:DMEASURE:MODE RMS
:MEASure:DMeasure:{SIGMA|SIGMB|SIGMC}
Function Sets or queries the delta computation mode for
wiring unit ΣA, ΣB, or ΣC.
Syntax :MEASure:DMeasure:{SIGMA|SIGMB|
SIGMC} {OFF|DIFFerence|P3W3_V3A3|
ST_DT|DT_ST}
:MEASure:DMeasure:{SIGMA|SIGMB|
SIGMC}?
:MEASURE:DMEASURE:SIGMA OFF
Example
:MEASURE:DMEASURE:SIGMA?
-> :MEASURE:DMEASURE:SIGMA OFF
Description The available options are explained below. The
modes that can be selected vary depending on
the wiring system of the specified wiring unit (ΣA,
ΣB, or ΣC).
OFF = No delta computation (only selectable with
a single-phase, two-wire system—1P2W)
DIFFerence = Differential voltage, differential
current (only selectable with a single-phase,
three-wire system—1P3W—or a three-phase,
three-wire system—3P3W)
P3W3_V3A3 = 3P3W-to-3V3A conversion (only
selectable with a single-phase, three-wire
system—1P3W—or a three-phase, three-wire
system—3P3W)
ST_DT = Star-to-delta conversion (only selectable
with a three-phase, four-wire system—3P4W)
DT_ST = Delta-to-star conversion (only selectable
with a three-phase, three-wire system that
uses the three-voltage, three current method—
3P3W(3V3A))
