DIODE AND CONTINUITY

 

Range 

Description 

  Remark

 

  

The display shows the approx. forward  Open Circuit Voltage

 

 

voltage drop of the diode.             

about 2.5V

 

 

   Max. 

Test 

Current:

 

 

   1mA

 

 

The built in buzzer will sound if the

 

 

resistance is less than about 30Ω.

 

 

The buzzer may not sound if the 

Open Circuit Voltage

 

 

resistance is between 30Ω and 100Ω.  about 2.5V

 

 

The buzzer will not sound if the 

 

 

resistance is more than 100Ω.

 

Overload Protection: 

250V DC/AC rms
