三、信號(hào)調(diào)整及說明（此操作僅在產(chǎn)品輸出精度不高時(shí)做微調(diào)用。正常情況下嚴(yán)禁使用?。?
在進(jìn)行以下調(diào)試時(shí)，請(qǐng)將產(chǎn)品通電預(yù)熱30分鐘，以達(dá)到最佳穩(wěn)定性。
3．1零信號(hào)的調(diào)整：輸入信號(hào)為零時(shí)，通過調(diào)零電位器，可將變送輸出信號(hào)調(diào)到所需 要的最低值。
3．2滿度信號(hào)調(diào)整：將信號(hào)輸入到滿度（最大值），通過量程電位器，將變送信號(hào)調(diào)到 所需要的最大量程值。
3．3反復(fù)操作3.1與3.2，直到調(diào)到所需要的值為止
四、外形尺寸
●安裝方式：
可固定安裝在35mm的標(biāo)準(zhǔn)導(dǎo)軌上
五、接線方式（具體以產(chǎn)品實(shí)物為準(zhǔn)）
