3.2.10 

电流测量

   

当开路电压对地之间的电压超过

250V

时,切勿尝试在电路上进行电流测量。如果

测量时保险管被烧断,可能会损坏仪表或伤害到您自己。

 

在电流测量档位,显示屏显示

“FUSE”

且蜂鸣器报警时,表示保险丝管熔断,更换本

仪表同规格的保险丝管。测量时,应使用正确的输入插座、功能档和量程。当测量
表笔被插在电流输入插座上的时候,切勿把测量表笔另一端并联跨接到任何电路上。
当测量电流大于

5A

时,测量时间不要超过

10

秒钟。

 

本仪表的直流电流量程为

6.000mA

60mA

600mA

20A

交流电流量程为

60mA

600mA

20A

 

测量电流:

 

 

将旋转开关转至合适档位。

 

注意:显示屏上会有一个

“LEAd”

符号短时间显示,以提醒需正确的表笔插孔设置。

 

 

把黑色测量笔连接到

COM

输入插座。如被测电流小于

600mA

时将红色测量笔

连接到

mA

输入插座;被测电流在

600mA~20A

间,将红色测量笔连接到

20A

输入插座。

 

 

断开待测的电路。把黑色测量笔连接到被断开的电路(其电压比较低)的一端,

把红色测量笔连接到被断开的电路(其电压比较高)的一端。

 

 

接上电路的电源,然后读出显示的读数。如果显示器只显示

“OL”

,这表示输入超

过所选量程,旋转开关应置于更高量程。

 

 

当测量电流大于

5A

时,测量时间不要超过

10

秒钟;

   

注意:当显示屏显示

“FUSE”

,并且蜂鸣器报警,表示保险丝熔断,请更换保险丝。

 

3.2.11  NCV

测量(非接触电压检测)

 

 

将旋转开关旋转

NCV

档位,将仪表顶部贴近目标体,如果仪表探测到交流电压,

仪表根据探测到的信号强度,蜂鸣器发出不同频率的报警声,蜂鸣器急促鸣叫说

明电压高或火线,鸣叫缓慢可能电压低或零线。

   

注意:

 

 

即使没有指示,电压仍然可能存在。不要依靠非接触电压探测器来判断导线是否

存在电压。探测操作可能会受到插座设计、绝缘厚度及类型不同等因素的影响。

 

 

当仪表输入端子输入电压时,由于感应电压的存在,电压感应指示灯亦可能会

亮。

 

 

外部环境的干扰源(如闪光灯,马达等)

,可能会误触发非接触电压探测。

 

3.2.12  LIVE

火线识别

 

 

将旋转开关旋转

NCV/LIVE

档位,按

“Select”

键切换

LIVE

测量,单根红色表笔插

插孔,表笔探针接触电源线线芯或插座金属片,蜂鸣器急促鸣叫,表示表

笔测量的是火线,如缓慢鸣叫或不鸣叫,表笔探针测量的是零线或地线。
