STPM01 calibration

Choosing R2 = 500 Ω (connected between V

Indicating with I
current, and with X
calculated, the final values for calibrators can be calculated as:
If the computed final calibration data would fall out of calibration data range, the energy
meter should be recognized as bad or the given presumptions and calculations above
should be checked. Otherwise, if the final data of calibrators would be written into energy
meter, the RMS readings should be very close to target values I and V and the frequency of
LED output should be very close to target value f.
