When measuring the magneto performance parameter ， we find that the instrument which use to measure voltage and current is still the simple voltmeter and amperemeter in the national standard ， and the form of wave that we observed is anomaly. based on the measure principles, it obviously ca n ' t be used to do quantitative analysis ； because the discharge process of ignition system is quite complex, accompanies with very strong electromagnetism interference, and the ignition current and voltage are variable ， it make the measure of ignition energy become a difficult thing of ignition system performance detection
在磁電機常規測量時，發現在國家標準中用於測量電壓、電流的儀器仍然是普通的電壓、電流表，而觀測到的波形多為不規則的形狀，根據測量原理，顯然不能用其來做定量的分析；由於點火系統的放電過程比較復雜，伴隨著很強的電磁干擾，點火電流、點火電壓都是變量，使得點火能量的測量成為點火系統性能測試的一個難點。 -
