儀錶維護

 

本節提供基本的維護資料,包括更換保險管和更換電池的說明。

 

除非您是有經驗的維修人員且有相關的校準、性能測量以及維修資料,否則不要嘗試去維

修本儀錶

 

4.1 

一般維護

   

 

為避免受到電擊或損壞儀錶,不可弄濕儀錶內部。在打開外殼或電池蓋前,必
須把測量筆和輸入信號的連接線拆除。

 

定期使用濕布和少量洗滌劑清潔儀錶外殼

請勿用研磨劑或化學溶劑。輸入插座如果弄髒

或潮濕可能會影響讀數。

 

清潔輸入插座:

 

 

關閉儀錶,並將所有測量筆從輸入插座中拔出。

 

 

清除插座上的所有髒物。

 

 

用新的棉花球沾上清潔劑或潤滑劑,清理每個插座,潤滑劑能

 

 

防止和濕氣有關的插座污染。

 

4.2 

更換電池及保險絲

 

 

為避免錯誤的讀數而導致受到電擊或人身傷害,儀錶顯示器出現

符號

時,應馬上更換電池。

   

測量電流時,如顯示幕顯示

“FUSE”

且蜂鳴器報警,表示保險絲熔斷,請更換保

險絲。

 

只能使用指定的保險絲

(500mA/250V,10A/250V 

速熔保險絲

為避免受到電擊或人身傷害,在打開電池蓋更換新電池之前,應關機並檢查測
量筆已從測量電路斷開。

 

更換電池或保險絲:

 

 

關斷儀錶電源。

 

 

將所有測量筆從輸入插座中拔出。

 

更換電池

 

 

用十字螺絲刀取出固定電池蓋的螺釘。

 

 

取下電池蓋。

 

 

拿掉舊電池,換上新的

9V 6F22

電池。

 

 

裝上電池蓋,上緊螺釘。

 

更換保險絲

 

 

拿掉防護膠套。

 

 

用十字螺絲刀取出固定儀錶後蓋的螺釘,取下儀錶後蓋。

 

 

拿掉損壞的保險絲,換上符合規格的新保險絲。

 

 

裝上儀錶後蓋,旋緊螺絲。裝上防護膠套。
