Three-phase energy meter field calibrator
Field settings:
Constant:
refers to the constant of the energy meter under test;
N:
refers to how many times of instrument pulse before an error is calculated. Specific to t he
mechanical energy meter, it is how many times of black pointers before an error is
calculated.
(It is worth noting that in the manual mode, press the manual switch after how many
times of black pointers show);
Active (reactive):
refers to the meter under test is an active or reactive meter;
Optoelectronic (manual):
pulse sampling method;
Input:
refers to the current sampling method (input the transformation ratio value; if it is a
direct-through meter, the transformation ratio is 1:1; otherwise input the other conditions in
accordance with on-site TA transformation ratio);
Transformation ratio:
the nominal value of the transformer nameplate.
Vector Graphics Area:
display the vector diagram of the relationship between voltage and
current vector at the time of measurement.
Error:
the error parameters resulting from on-site check by energy meter. The instrument
according to the input meter parameters generated and captured by the energy meter
shows three consecutive errors of the meter by high-precision computing and processing
the ratio error of the processed power consumption value measured and calculated by the
