ratio is 1:1 and it is input under other situations according to the transformation ratio of field TA); Error: the error parameters generated by the energy meter during field calibration. The instrument can calculate the percentage of the values of electric quantity measured by the energy meter and the difference in electric quantity actually measured by a standard meter according to the input energy meter constant and collected energy meter power pulses). - Page 9 parameter value by pressing [Confirm] key. Electric meter series Electric meter series: refers to the level of the measured energy meter, which will be indicated on the electric meter. Operation method: press "←, →" and the cursor jumps to the electric meter series setting; press [Confirm] key and jump out of a variety of options;...
- Page 10 Ratio: generally select the default value. Notes to the calibration parameter settings: The difference between "photoelectric" mode and manual mode is large. For example: check the three-phase mechanical active energy meter, and the electric energy constant is 450 r/kW. h and the set number of laps is 2. When calibrating by use of the photoelectric mode, every time when the energy meter’s black mark moves a lap, the photoelectric sampler generates a pulse;...
