52 / 60 page  STPM01 calibration STPM01 52/60 Doc ID 10853 Rev 8 VDIV = (XV * VBG)/ (2 * GDIF * AV * Kv * GDF * GINT * BV)= 145,6 mV Choosing R2 = 500 Ω (connected between V I and VSS), the R1 resistor (connected between VLINE and VIP) value is obtained: R1 = R2 * (Vn - VDIV) / VDIV = 789,3 Ω Indicating with IA and VA the real readings on the STPM01 RMS registers of voltage and current, and with XI and XV ideal values of RMS current and voltage readings already calculated, the final values for calibrators can be calculated as: XV = (Kv * VA) / 0.875 XI = (Ki * IA) / 0.875 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. |
