Measure Resistance 
1.  Turn the rotary switch to 
D. Make sure power is disconnected from the circuit to be 
measured. 
2.  Connect the red test lead to the J terminal and the black test lead to the COM 
terminal. 
3.  Measure the resistance by touching the probes to the desired test points of the circuit.  
4.  Read the measured resistance on the display. 
Test for Continuity 
With the resistance mode selected, push the YELLOW button once to activate the continuity 
mode. If the resistance is <70 Ω, the beeper sounds continuously, designating a short circuit. 
If the Product reads 
o
, the circuit is open.
