Meter Functions 

–Audible Continuity (        )

 

 

 
IMPORTANT:  Turn  the  power 
OFF on the test circuit 

 

Select the 

Audible Continuity 

(      )  function  with  the  rotary 
switch and mode button 

Insert: 

  Black lead in 

COM

 terminal. 

 

  Red  lead  in 

V-

Ω

-RPM 

terminal. 

 
Connect  one  test  probe  to  each 
end of the circuit to be tested. 
 

  Circuit complete, the meter will 

beep continuously. 

 

  Circuit  open,  there  is  no  beep 

and  the  display  shows  to  OL 
(over limit). 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

Meter Functions 

–AC or DC Current (A)

 

 

 

IMPORTANT: All current measured 
flows through the meter. 

It is important that you do not: 

 

Measure  current  greater  than 

600  Volts  AC  or  DC,  with 
respect to ground. 

 

Do  Not  Exceed  30  seconds 

when  measuring  continuous 
current 

between 

1A-20A. 

Allow  five  minutes  for  cool 
down before continuing. 

 

Select  the 

20A.

,

  mA 

or

 

μA 

range with the rotary switch. 
 
Press  the 

Mode 

button  to 

select 

AC 

or

 DC.

 

 

Insert: 

  Black lead in 

COM

 terminal. 

 

  Red  lead  in  the 

20A

  or 

mA 

terminal  (select  20A  if  you  are 
unsure of the current draw).               

 

IMPORTANT: Turn OFF all power 
to  the  circuit  or  disconnect  the 
circuit from the power source. 

 

Connect: 

  The Red probe to the side of the 

circuit  closest  to  the  power 
source. 

 

  The Black probe to the side of 

the circuit to ground. 

 

  Turn the power ON and test. 

 

 

Note: 
Current 

must 

always 

be 

measured  with  the  meter  test 
probes  connected  in  series, 
as described.
