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>),
(<NRf>|ORDer<1-50>)|OFF}
<harmonic analysis function>={VTHD|V|
VCON|ATHD|A|ACON|PF|W|WCON|VDEG|ADEG}

FUNCTION PF,1
Description
• Except for the case when it is OFF, you will
specify <harmonic analysis function>,
<element>, and <order> for the relay output item.
However, if the <normal measurement function>
is set to VTHD, ATHD, or PF, <element> is
ignored. <element> can be omitted in this case.
(The response to the query will have the
<element> 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 three decimal places.
1.000 to 9999: Rounded to four significant digits.
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

items in case of normal measurement.

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>|
OFF}
<x>=1 to 4
<normal measurement function>={V|A|W|VA|

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 item.
However, if the <normal measurement
function> is set to MATH, <element> is
ignored. (The response to the query will
have the <element> omitted.)
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

:RELAY:
NCHANNEL3:THRESHOLD 1.200E+03
Description
The mantissa of the setting value is rounded a
follows.
Less than 1.000: Rounded to three decimal places.
1.000 to 9999: Rounded to four significant digits.
RELay:STATe
Function
