* Numeric Data Format
(1) Normal Data
• Phase difference φ (PHI) of a power
measurement element 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 the power value (P, S, Q, PC)
• Integrated value (WH, WHP, WHM, AH, AHP,
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: [-]123.45E+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 Numeric Data Output Items That Are Preset
The list of function names used in the commands and
the corresponding function names used on the screen
menu of the WT1600FC is given in the Function
Selection List in the DISPlay group.
Note
The List of Numeric Data Output Items That Are Preset indicates
the measurement function and element that are assigned to each
item number (ITEM<x>). Items that are not set to be measured
are displayed or output in the same fashion as when the data
does not exist. For example, if frequency FI of the current of
element 2 is not set to be measured, the output of item number
ITEM19 is the same as the output when the data does not exist
(NAN for ASCII).
