6.18 NUMeric Group
:NUMeric:FLICker:FUNCtion:CLEar
Function Clears (sets to NONE) the output items of
measured flicker data (variable format).
:NUMeric:FLICker:FUNCtion:
Syntax
CLEar {ALL|<NRf>[,<NRf>]}
ALL = Clears all items
1st <NRf> = 1 to 32 (item number to start
clearing)
2nd <NRf> = 1 to 32 (item number to stop
clearing)
:NUMERIC:FLICKER:FUNCTION:CLEAR ALL
Example
Description • Only available with the flicker measurement
function (/FL option).
• If the 2nd <NRf> is omitted, the output items
from the start clear number to the last item (32)
are cleared.
:NUMeric:FLICker:FUNCtion:DELete
Function Deletes the output items of measured flicker data
(variable format).
:NUMeric:FLICker:FUNCtion:
Syntax
DELete {<NRf>[,<NRf>]}
1st <NRf> = 1 to 32 (item number to start
deleting)
2nd <NRf> = 1 to 32 (item number to stop
deleting)
:NUMERIC:FLICKER:FUNCTION:DELETE 1
Example
(Deletes ITEM1 and shifts ITEM2 and subsequent
items forward)
:NUMERIC:FLICKER:FUNCTION:
DELETE 1,3
(Deletes ITEM1 to 3 and shifts ITEM4 and
subsequent items forward)
Description • Only available with the flicker measurement
function (/FL option).
• Output items subsequent to the deleted output
items are shifted in order into the deleted items'
position, and NONE is set in the open positions
on the end.
• If the 2nd <NRf> is omitted, only the output
item of the start delete number is deleted.
:NUMeric:FLICker:FUNCtion:ITEM<x>
Function Sets output items (function, element, and
observation period) of measured flicker data
(variable format) or queries the current setting.
:NUMeric:FLICker:FUNCtion:
Syntax
ITEM<x> {NONE|<Function>,
<Element>[,<Period>]}
:NUMeric:FLICker:FUNCtion:ITEM<x>?
<x> = 1 to 32 (item number)
NONE = No output items
<Function> = {TIME|UN|FU|DC|DMAX|DT|
TMAX|PST|PLT}
<Element> = {<NRf>} (<NRf> = 1 to 4)
<Period> = {CURRent|<NRf>|ALL}
(<NRf> = 1 to 99)
6-86
:NUMERIC:FLICKER:FUNCTION:
Example
ITEM1 DC,1,1
:NUMERIC:FLICKER:FUNCTION:ITEM1? ->
:NUMERIC:FLICKER:FUNCTION:
ITEM1 DC,1,1
Description • Only available with the flicker measurement
function (/FL option).
• The contents that are output for each of the
selections for <Function> are as follows:
<Function>
Output Contents
TIME
Elapsed measurement time [sec] Not required Not required
(the time displayed under Flicker: in the upper right part of
the screen)
UN
RMS voltage (rated voltage) Un[V] Required
FU
Voltage frequency Freq[Hz]
DC
Relative steady-state voltage
change dc[%]
DMAX
Maximum relative voltage
change dmax[%]
DT
Relative voltage change time
d(t)[ms]
TMAX
Tmax[ms]
PST
Short-term flicker value Pst
PLT
Long-term flicker value Plt
• When <Element> is omitted, Element 1 is set.
• The contents of the selections for <Period> are
as follows. If <Period> is omitted, CURRent is
set.
CURRent
currently being measured (rows of the numeric
list marked with an asterisk (*) in the flicker
measurement display screen).
When in measurement complete status, same
as ALL.
ALL Overall observation period (Result row
of the numeric list in the flicker measurement
display screen).
<NRf> = 1 to 99 Specified observation period.
• <Element> or <Period> is omitted from the
response to the output items in the table
above for which specification of <Element> or
<Period> is not required.
• TMAX, a new function defined in IEC61000-
3-3 Ed3.0, can be used. TMAX represents the
same content as the conventional DT function,
and the measured data that is output is also
the same.
