style="text-indent:25px">相位差測量兩個正弦電量可以是電壓和電流，或者一個是電壓，一個是電流等，對應(yīng)點(diǎn)通常是從負(fù)到正的過零點(diǎn)，相當(dāng)于正弦電函數(shù)的初始相位角。相位差的單位是度或弧度，正負(fù)號表示超前或滯后關(guān)系。一種由于被測相位差正弦電量的頻率范圍很寬，所以通常根據(jù)頻率選擇測量方法和儀器。常用的方法有直接法和間接法，江蘇KOBRA相位差測量儀質(zhì)量推薦。一種直接法：用指針式相位計(jì)、數(shù)字相位計(jì)等**儀器或用負(fù)示波器測量相位差。當(dāng)使用陰極示波器時，江蘇KOBRA相位差測量儀質(zhì)量推薦，將兩個相同頻率的正弦電壓信號分別加到示波器的X軸和Y軸上，江蘇KOBRA相位差測量儀質(zhì)量推薦。然后兩個正弦電壓之間的相位差為∮=電弧正弦（B/α）。測量波段：550nm單波段，上料方式：手動上料。江蘇KOBRA相位差測量儀質(zhì)量推薦</p><div
