安全的保养习惯

 

 

打开仪表外壳或拆下电池盖时,应先拔出测量笔。

 

 

维修仪表时,必须使用指定的替换零部件。

 

 

在打开仪表前,必须断开一切有关的电源,同时也必须确保您没带有静电以免损

坏仪表的元器件。

 

 

仪表的校准以及维修操作必须由专业人员操作。

   

 

打开仪表外壳时,必须注意到仪表内的一些电容即使在仪表关闭电源以后还保存

着危险的电压。

 

 

如果观察到仪表有任何异常

该仪表应立即停止使用并送维修。并确保在检查合

格前不能被使用。

 

 

当长时间不用时,请将电池取下,并避免存放于高温高湿的地方。

 

1.2 

输入保护措施

 

 

在进行电压测量时,可承受最高输入电压是直流电压

1000V

或交流电压

750V

 

 

在进行频率、电阻、通断和二极管测量时,可承受不超过交流电压

250V

或等效

的有效值电压。

 

 

在进行

mA

电流测量时,通过保险管(

F500mA/250V

)进行保护;在进行
