The single-phase energy meter calibrator is a set of 0.1-magnitude high precision field calibration instrument, but it is qualitatively different from the single-phase field calibration made of energy meter chip.
Where there is no load on the spot, its current output can be used as a virtual load, which is greatly convenient for field testing of single-phase energy meter.

Storage and query
HA can store at least 6000 calibration records, which can be searched according to different ways and support for fuzzy queries, and you can inquire the calibration record data stored in the instrument.
Calibration plan
Before work, users can make task plans on the HA, which is beneficial to orderly working. Calibration plan can be downloaded via PEC management software through serial port into the instrument.
Input: the instrument supports for Chinese characters, English case and Arabic number input.
Harmonic measurement: shows the content of 2nd ~ 51st harmonics in the form of histogram.
Counter: check the accuracy of meter counter.
U disk: upload and download data by connecting U disk
Timing: calibrate the instrument time
Waveform display: shows U and I waveforms directly.
User functionality: view the uploaded user information and do corresponding tests.
Field settings:
Constant refers to the measured energy meter's constant;
N: refers to error calculation at a time by the instrument within how many times of pulses. Specifically, as for a mechanical energy meter, it is error calculation at a time by black meter for how many times. (It is noteworthy that in manual mode, the manual switch is pressed once for how many times of black meter);
Photoelectric (manual): pulse sampling way; (note: photoelectric head and pulse line are in the photoelectric sampling mode)
Input: refers to current sampling way (there is a need to input the numerical value of transformation ratio and input the transformation ratio; if it is a straight meter, the transformation 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).
Electrical parameter area:
The following kinds of all electrical parameters are shown:
U (V), I (A), φ(Angle), F (frequency), P (W), Q (Var), COSФ
U (field voltage value) I (field current value) φ (phase shift angle) P (active value)Q (reactive value) φ (power factor) F (frequency)
Input method identification: "123" means Arabic numeral input, "ABC" refers to English uppercase characters input, "ABC" means English lowercase characters input, and "Pin" is Chinese character input.
