Even if you would not use any soldering past, but preforms without flux, you will get a perfect wettening of the surfaces and a voidless connection. 即使你之前沒(méi)有進(jìn)行過(guò)焊接，而且焊片不帶焊劑，焊接面也可以得到良好的潤濕，并且空率很低。
This tester is provided with a "Guard" terminal to prevent errors due to surface leakage. 本儀表裝有保護環(huán)接線(xiàn)柱，用以糾正因表面漏電而造成的誤差。
Apply a thin coating of petroleum jelly or chassis grease to the exposed surfaces of the cable terminal clamps and the battery terminal posts. 為電纜終端線(xiàn)夾和電池接線(xiàn)柱露出部分涂一層薄的凡士林油或車(chē)用底盤(pán)滑脂。
