11.4 Output Format for Normal Measured/Computed
Data, Harmonic Analysis Data, Set-up

Parameters and Error Codes

Output Format of Normal Measured/Computed Data
11-4
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
h1 to h3: data type
V_ _
: voltage
VA_
: Apparent power
HzV
: Voltage frequency
Ah_
: Ampere hour
Apk
: Peak current value
CV2
: V2 crest factor
CA2
: A2 crest factor
A+B
: (display A)+(display B)
A * B
: (display A) * (display B)
Wh+
: Positive watt hour
Ah+
: Positive ampere hour
HMS : Elapsed time of integration
(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
h1-h4: data type (only when the computing equation is A/B
ROM version 2.01 or later)
2
A/B
: (display A)/(display B)

A
/B: (display A)

h5: Data state
N: normal
I: Overrange
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
Data Section
The data section consists of 11 bytes.
