5.15 MEASure Group

The commands in this group deal with computation.
You can make the same settings and queries that you can make by pressing MEASURE, FREQ MEASURE
(SHIFT+MEASURE), and AVG on the front panel or by pressing WIRING on the front panel and then using the η
Formula or Δ Measure (/DT option) menu.
:MEASure?
Function Queries all computation settings.
:MEASure?
Syntax
:MEASure:AVERaging?
Function Queries all averaging settings.
:MEASure:AVERaging?
Syntax
: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 (option) is only valid when TYPE is set
to EXPonent (attenuation constant). For details,
see the features guide, IM WT1801-01EN.
:MEASure:AVERaging[:STATe]
Function Sets or queries the on/off status of averaging.
:MEASure:AVERaging[:
Syntax
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 (option) is only valid when the type is
set to EXPonent. For details, see the features
guide, IM WT1801-01EN.
5-70
:MEASure:DMeasure?
Function Queries all delta computation settings.
:MEASure:DMeasure?
Syntax
Description This command is only valid on models with the
delta computation (/DT) option.
:MEASure:DMeasure:MODE
Function Sets or queries the voltage or current mode that
is used in delta computation.
:MEASure:DMeasure:MODE {RMS|MEAN|
Syntax
DC|RMEAN|AC}
:MEASure:DMeasure:MODE?
:MEASURE:DMEASURE:MODE RMS
Example
:MEASURE:DMEASURE:MODE? ->
:MEASURE:DMEASURE:MODE RMS
Description This command is only valid on models with the
delta computation (/DT) option.
:MEASure:DMeasure:{SIGMA|SIGMB|
SIGMC}
Function Sets or queries the delta computation mode for
wiring unit ΣA, ΣB, or ΣC.
:MEASure:DMeasure:{SIGMA|SIGMB|
Syntax
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 • This command is only valid on models with the
delta computation (/DT) option.
• 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))
