Making Basic Measurements 
The figures on the following pages show how to make basic 
measurements.  
When connecting the test leads to the circuit or device, connect 
the common (COM) test lead before connecting the live lead; 
when removing the test leads, remove the live lead before 
removing the common test lead. 
XWWarning 
To avoid electric shock or injury, or damage to the 
Meter, disconnect circuit power and discharge all high-
voltage capacitors before testing resistance, continuity, 
diodes, or capacitance.
