:NUMeric[:NORMal]:VALue?
Function Queries the numerical data for normal
measurement.
Syntax :NUMeric[:NORMal]:VALue? {|<NRf>}
<NRf> = 1 to 255 (item number)
Example • Example when <NRf> is specified
:NUMERIC:NORMAL:VALUE? 1 ->
104.75E+00
• Example when <NRf> is omitted
:NUMERIC:NORMAL:VALUE? ->
104.75E+00,105.02E+00,-0.38E+00,
..(omitted)..,49.868E+00
• Example in which “
:NUMeric:FORMat
” is set
to “Float”
:NUMERIC:NORMAL:VALUE? -> #4
(Number of bytes, 4 digits)(Series of data
bytes)
Description • If <NRf> is specified, only the numerical data
of the item number is output.
• If <NRf> is omitted, the numerical data of item
numbers from 1 to “
:NUMeric:[:NORMal]:
NUMber
” is output in order.
• For the format of the individual numerical data
that is output, see “Numerical Data Format” at
the end of this group (section).
* Numerical Data Format
(1) Normal Data
• Phase difference
φ
(PHI) of elements 1 to 6 in 180
°
(Lead/Lag) display
ASCII: “D/G” + <NR3> format (mantissa: maximum
significant digits = 5, exponent: 2 digits, example:
G90.00E+00)
FLOAT: IEEE single-precision floating point (4-byte)
format
•
Σ
of power values (P, S, Q, and PC)
• Integrated values (WH, WHP, WHM, AH, AHP, and
AHM)
ASCII: <NR3> format (mantissa: maximum significant
digits = 6, exponent: 2 digits, example: [-]123.456E+00)
FLOAT: IEEE single-precision floating point (4-byte)
format
• Elapsed time of integration (TIME)
ASCII: <NR1> format in units of seconds (example:
for 1 hour (1:00:00), 3600)
FLOAT: IEEE single-precision floating point (4-byte)
format in units of seconds (example: for 1 hour
(1:00:00), 0x45610000)
• No items (NONE)
ASCII: “NAN” (Not a Number)
FLOAT : 0x7E951BEE (9.91E+37)
• Other than above
ASCII: <NR3> format (mantissa: maximum significant
digits = 5, exponent: 2 digits, example: [-]
123.45.456E+00)
FLOAT: IEEE single-precision floating point (4-byte)
format
(2) Error Data
• Data does not exist (display: “————”)
ASCII: “NAN” (Not A Number)
FLOAT: 0x7E951BEE(9.91E+37)
• Over the range (display: “—O L—”)
• Overflow (display: “—O F—”)
• Data over (display: “ Error ”)
ASCII: “INF” (INFinity)
FLOAT : 0x7E94F56A(9.9E+37)
* List of Numerical Data Output Items That Are
Preset
The function names used in commands and their
corresponding names that appear in the
instrument's on-screen menu are shown in the
function selection list for the DISPlay Group.
Note
The List of Numerical Data Output Items That Are Preset
shows the measurement functions and elements assigned
to each item number (ITEM<x>). For items not assigned
to a measurement object, the same display is output as
that for when data does not exist. For example, if the
frequency FI of the current in element 2 is not to be
measured, the indicator for non-existent data (“NAN” for
ASCII) is output on item number 19.
