Output Format of Normal Measured/Computed Data
Data Format
Measured data normally consists of a 6-byte header and 11 bytes of data
Header Data
Header Section
The header section consists of 6 bytes (h1 to h6).
h1 h2 h3 h4 h5 h6
h1 to h3: data type
V_ _ : voltage A_ _ : Current W_ _ : Active power
VA_ : Apparent power Var : Reactive power PF_ : Power factor
HzV : Voltage frequency HzA : Current frequency Wh_ : Watt hour
Ah_ : Ampere hour DEG : Phase angle Vpk : Peak voltage value
Apk : Peak current value EFF : Efficiency CV1 : V1 crest factor
CV2 : V2 crest factor CV3 : V3 crest factor CA1 : A1 crest factor
CA2 : A2 crest factor CA3 : A3 crest factor
A+B : (display A)+(display B) A–B : (display A)–(display B)
A
*
B: (display A)
*
(display B) A/B : (display A)/(display B)
Wh+ : Positive watt hour Wh– : Negative watt-hour
Ah+ : Positive ampere hour Ah– : Negative ampere hour
HMS : Elapsed time of integration MEM : Data number in case of recalling
(Efficiency, crest factor, and the results of four arithmetic operations can be output on
WT110/WT130 with ROM version 2.01 and later. However, different instruments have
different restrictions on the output of these parameters.)
h4: Element
1: Element 1 2: Element 2 3: Element 3 4: ∑
h1-h4: data type (only when the computing equation is A/B

ROM version 2.01 or later)

h5: Data state
N: normal I: Overrange O: Computation overflow P: Peak overflow
E: No data
h6: Indicates data lag/lead in case of DEG data type. In case of other data types, _ (space) will
occur.
G: Lag D: Lead _: Not detectable
Data Section
The data section consists of 11 bytes.
d1 d2 d3 d4 d5 d6 d7 d8 d9 d10 d11
d1 : polarity; _ (space) or – (minus)
d2 to d8 : mantissa, floating-point number of the maximum six digits
d9 to d11 : exponent; E-3→m, E+0, E+3 → k, E+6 → M
Data state in case of an overrange (“oL” is being displayed)
h1 h2 h3 h4 I _ _ 9 9 9 9 9 9 . E + 3
Data state in case of a computation overflow
(“oF”, “PFErr”, “dEGEr”, “ErrLo”, “ErrHi” is being displayed)
h1 h2 h3 h4 O _ _ 8 8 8 8 8 8 . E + 0
Data state in case of no data (when the display is - - - - -)
"I" becomes "E" for data during overrange.
