XWWarning 
To avoid possible electric shock or personal injury, inspect the 
test leads for damaged insulation or exposed metal. Check the 
test leads for continuity. Replace damaged test leads before 
using the Meter. 
Precautions and Safety Information 
In this manual, a Warning identifies conditions and actions that pose hazard(s) to the 
user; a Caution identifies conditions and actions that may damage the Meter or the test 
instruments. 
XWWarning 
To avoid possible electric shock or personal injury, follow these 
guidelines: 
•  Use this Meter only as specified in this manual or the 
protection provided by the Meter might be impaired. 
•  Do not use the Meter if it is damaged. Before using the 
Meter, inspect the case. Look for cracks or missing plastic. 
Pay particular attention to the insulation surrounding the 
connectors. 
•  Make sure the battery door is closed and latched before 
operating the Meter. 
•  Replace the battery as soon as the battery indicator (M) 
appears. 
•  Remove test leads from the Meter before opening the 
battery door. 
•  Inspect the test leads for damaged insulation or exposed 
metal. Check the test leads for continuity. Replace damaged 
test leads before using the Meter. 
•  Do not apply more than the rated voltage, as marked on the 
Meter, between the terminals or between any terminal and 
earth ground. 
•  Never operate the Meter with the cover removed or the case 
open.   
•  Use caution when working with voltages above 30 V ac rms, 
42 V ac peak, or 60 V dc. These voltages pose a shock 
hazard. 
•  Use only the replacement fuses specified in this manual. 
•  Use the proper terminals, function, and range for 
measurements. 
•  Avoid working alone. 
•  When measuring current, turn off circuit power before 
connecting the Meter in the circuit. Remember to place the 
Meter in series with the circuit.
