Normal Data
• Frequency (FU and FI)
ASCII: <NR3> format (mantissa: 5 digits, exponent: 2 digits, example: 50.000E+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)
F LOAT: IEEE single-precision floating point (4-byte) format in units of seconds
(example: for 1 hour (1:00:00), 0x45610000)
• Peak information (PKU, PKI, PKSPeed, PKTorque) for Cycle by Cycle measurement
No peak " ":
Positive peak "↑+":
Negative peak "↓ - ":
Positive and negative peak " ↑ ↓ ±":
Note
If the main unit's peak over detection function makes a detection during the measurement
period, 4 is added to the numbers above.
• No items (NONE)
ASCII: "NAN" (Not A Number)
FLOAT: 0x7E951BEE (9.91E+37)
• Other than above
A SCII: <NR3> format (mantissa: maximum significant digits = 6, exponent: 2 digits,
example: [-]123.456.45E+00)
FLOAT: IEEE single-precision floating point (4-byte) format
Error Data
•
Data does not exist (display: "---------")
ASCII: "NAN" (Not A Number)
FLOAT: 0x7E951BEE (9.91E+37)
•
Overrange (display: "---O L---")
•
Overflow (display: "---O F---")
•
Data over (display: "Error ")
ASCII: "INF" (INFinity)
FLOAT: 0x7E94F56A (9.9E+37)
Note
• For the 180° (Lead/Lag) display of the phase difference φ (PHI) of elements 1 to 4, the values
are output in the range between -180.000 to 180.000 with lead (D) and lag (G) set to negative
and positive values, respectively.
• For the Σ of power values (P, S, Q, and PC), the number of digits of the mantissa may be
equal to 7 (the maximum significant digits) depending on the combination of the voltage
range and current range (power range). See the list of power ranges in the User's Manual IM
WT3001E-01EN.
