Data Format Description:
Power with 2-byte register (0-9999)
and 1-byte decimal register (0-15)
describe the electric data. Power
register show the BCD part, decimal
point registers show the exponent of
electric data.
For example:
A phase voltage representation:
The register UA = 0DACH (3500);
register DPT = 5;
UA = 0.3500 × 10 ^ 5 = 35.00kV.
A phase current representation:
The register IA = 0FA0H (4000);
register DCT=3;
IA = 0.4000 × 10 ^ 3 = 400.0A.
Note:
Frequency and power factor
use fixed exponent to calculation.
XXHz (DHZ = 2); 0.XXX (DPF = 0)
Note:
1. Not all of the data can be read by RS485, the reading address will be unsuccessful.
2. The data can be read out depends on your multi-function meter model, please refer to the
corresponding product manual before build your software.
3. Some software have different definitions of the start bit of register address, there will be
offset, please add 1 for the right address. To get more info, please contact technical
support
