防爆(bao)磅秤維修故障(zhang)解決方案：

（1）稱重物移除后無法回到零點的故障分析檢查傳感器輸出信號值是否于標準內（A/D的總放大碼/使用內碼范圍/底碼范圍），如果信號值未在標準內，調節傳感器可調電阻，將信號值調到標準內，如無法補償請檢查傳感器是否有問題，在保證傳感器輸出正常（秤體穩定）情況下，鎖定儀表故障，一般是放大電路及A/D轉換電路發生問題，再依據電路原理逐一判斷測試分析，以zui終解決問題。（2）稱量不準確的故障分析觀測內碼值是否穩定，傳感器各部位是否有摩擦現象，穩壓電源是否穩定，運放電路是否正常，使用砝碼測試秤盤四腳秤量是否平均。依照說明書指示，進一步做儀表局部分析或重量校正。（3）無法開機的故障先確定非保險絲、電源開關、電源線及電壓切換開關的問題所造成，檢查變壓器有無交流電壓輸入及交流電輸出。如果儀表帶有電池將電池取下再以AC電源開機，以了解是否為電池電壓不足所造成。其次再檢測整流電路、穩壓電路以及顯示驅動電路是否出現異常，如果這些都沒問題檢查處理器及附屬電路是否燒壞。安塞滾筒電子稱*延長帶打印吊秤
