Meter Functions – Audible Continuity (     )

 

 

 
IMPORTANT: Turn the power OFF 
on the test circuit 

 

Select the 

Audible  Continuity 

   “  function  with the function 

dial and 

mode

 button. 

Insert: 

  Black lead in 

COM

 terminal. 

  Red lead in 

V-

Ω

-RPM 

terminal. 

 
Touch  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 Exceed 30 seconds when 

measuring continuous current 
between 1A-20A. Allow five 
minutes for cool  down before 
continuing with any other 
measurements. 

 

Select the “

20A”

  or

  “mA” 

range 

with the function dial. 
 
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 tes

Meter Functions –Temperature (°C / °F )

 

 

 

IMPORTANT: To avoid heat 
damage to the meter, keep it 
away from sources of very high 
temperature.  The life of the 
Temperature  Probe is also 
reduced when subjected to 
very high temperatures. Probe 
operating range is   
–58

to 482

 o

F. 

 

Select the 

T

emperature 

  “°C  or  °F” 

function  with the 

function dial. 

 

Insert the temperature probe 

connector into the K-type 
thermocouple adapter.    Insert the 
adapter into the front of the meter 
as shown. 

Touch the end of the  temperature 
sensor to the area or surface of 
the object to be measured. 

 

Note: 
Current must always be 
measured with the meter 
test probes connected in 
series, as described.
