Continuity

Note: 

When the resistance is between 50Ω and 150Ω, the buzzer 

        may or may not sound. When the resistance is more than 150Ω, 

        the buzzer will not sound.

Plug in terminal for black test lead.

5.   terminal

 

Plug in terminal for the red test lead.

6. 

rANGe/           Button

 

(i) In voltage, current or resistance measurement function this button is used to switch between autorange mode and manual range  

 mode

 

as well as to select desired manual range.

 

 

(ii) In continuity or diode test function, this 

rANGe/            

button is used to switch between continuity and diode test functions.

7. 

HOld Button

 

Used to enter/exit data Hold mode.

8.

  

 

 

 

In dc current measurements this button is used for zeroing before measurement. 

 

In other measurements, this button can be used to enter/exit Relative mode.

9. 

finger guard

10. Jaws

 

Used to clamp conductor for current measurements.

 Buzzer

 

Buzzer sounds if a button is pressed. 

 

Before the meter turns off automatically, the meter will emit 5 short beeps, 1 minute later it will emit a long beep then turn off  

 

 automatically.
