RELay:HCHannel<x>:FUNCtion
Function
Sets the function of the relay output item in case of
harmonic analysis/queries the current setting.
Syntax
RELay:HCHannel<x>:FUNCtion {<harmonic
analysis function>,(<NRf>|ELEMent<1-3>),
(<NRf>|ORDer<1-50>)|OFF}
<harmonic analysis function>={VTHD|V|VCON|
ATHD|A|ACON|PF|W|WCON|VDEG|ADEG}
Example
RELAY:HCHANNEL1:FUNCTION V,1,1
RELAY:HCHANNEL1?
→
:RELAY:HCHANNEL1:
FUNCTION V,1,1
RELAY:HCHANNEL2?
→
:RELAY:HCHANNEL2:
FUNCTION OFF
RELAY:HCHANNEL4?
→
:RELAY:HCHANNEL4:
FUNCTION PF,1
Description
• The order setting will be ignored in case the
harmonic analysis function is set to VTHD, ATHD
or PF and might therefore be omitted.
• Even if V,A or W has been selected, the rms value of
the 1st to 50th order does not become the
corresponding relay output item. Also, even if
VDEG or ADEG has been selected, the phase angle
between the 1st order voltage and 1st order current
does not become the corresponding relay output
item.
RELay:HCHannel<x>:THReshold
Function
Sets the threshold level for the relay output item in
case of harmonic analysis/queries the current setting.
Syntax
RELay:HCHannel<x>:THReshold {<NRf>}
<x>= 1 to 4
<NRf>= 0.000E+00 to
±
9.999E+09
Example
RELAY:HCHANNEL1:THRESHOLD 600.0E+00
RELAY:HCHANNEL1:THRESHHOLD?
→
:RELAY:
HCHANNEL1:THRESHOLD 600.0E+00
Description
The mantissa of the setting value is rounded a follows.
Less than 1.000 : Rounded to the third digit left of the
decimal.
1.000 to 9999
: Rounded to the fourth significant
digit.
RELay:MODE
Function
Sets the mode of the comparator function/queries the
current setting.
Syntax
RELay:MODE {SINGle|DUAL}
RELay:MODE?
Example
RELAY:MODE DUAL
RELAY:MODE?
→
:RELAY:MODE DUAL
RELay:NCHannel<x>?
Function
Queries all settings related to the relay output items in
case of normal measurement.
Syntax
RELay:NCHannel<x>?
<x>=1 to 4
Example
RELAY:NCHANNEL2?
→
:RELAY:NCHANNEL2:
FUNCTION A,1;
THRESHOLD 20.00E+00
RELay:NCHannel<x>:FUNCtion
Function
Sets the function of the relay output item in case of
normal measurement/queries the current setting.
Syntax
RELay:NCHannel<x>:FUNCtion {<normal
measurement function>,(<NRf>|ELEMent<1-3>|
SIGMa)|OFF}
<x>=1 to 4
<normal measurement function>={V|A|W|VA|VAR|
PF|DEGRee|VHZ|AHZ|WH|WHP|WHM|AH|AHP|AHM|MATH|
VPK|APK}
Example
RELAY:NCHANNEL3:FUNCTION W,1
RELAY:NCHANNEL3?
→
:RELAY:NCHANNEL3:
FUNCTION W,1
Description
• Except for the case when it is OFF, you will specify
<normal measurement function> and <element> for
the relay output function. However, if the <normal
measurement function> is set to MATH, <element>
is ignored. (The response to the query will have the
<element> omitted.)
• For the meanings of the symbols of functions, see
Note on page App2-11.
RELay:NCHannel<x>:THReshold
Function
Sets the threshold level for the relay output item in
case of normal measurement/queries the current
setting.
Syntax
RELay:NCHannel<x>:THReshold {<NRf>}
<x>=1 to 4
<NRf>=0.000E+00 to
±
9.999E+09
Example
RELAY:NCHANNEL3:THRESHOLD 1.200E+03
RELAY:NCHANNEL3:THRESHHOLD?
→
:RELAY:
NCHANNEL3:THRESHOLD 1.200E+03
Description
The mantissa of the setting value is rounded a follows.
Less than 1.000 : Rounded to the third digit left of the
decimal.
1.000 to 9999
: Rounded to the fourth significant
digit.
RELay:STATe
Function
Sets the comparator function ON/OFF, queries the
current setting.
Syntax
RELay[:STATe] {<Boolean>}
RELay:STATe?
Example
RELAY ON
RELAY:STATE ON
RELAY:STATE?
→
:RELAY:STATE 1
