Terms in this manual 
WARNING  

identifies conditions and actions that could result in serious injury or even 
death to the user. 

identifies conditions and actions that could cause damage or malfunction 
in the instrument. 

 
This manual contains information and warnings that must be followed for operating the 
instrument safely and maintaining the instrument in a safe operating condition. If the 
instrument is used in a manner not specified by the manufacturer, the protection 
provided by the instrument may be impaired. The meter is intended only for indoor use. 
 
The meter protection rating, against the users, is double insulation per IEC61010-1 2nd 
Ed., EN61010-1 2nd Ed., UL61010-1 2nd Ed. and CAN/CSA C22.2 No. 61010.1-0.92 to 
Category II 1000V AC & DC. 
Terminals (to COM) measurement category: 
V : 

Category II 1000V AC & DC 

A & mA

A : Category II 450V AC & DC 

 
Per IEC61010-1 2nd Ed. (2001) Measurement Category 
Measurement Category II (CAT II) is for measurements performed on circuits directly 
connected to the low voltage installation. Examples are measurements on household 
appliances, portable tools and similar equipment. 
 
WARNING  
To reduce the risk of fire or electric shock, do not expose this product to rain or 
moisture. To avoid electrical shock hazard, observe the proper safety precautions when 
working with voltages above 60 VDC or 30 VAC rms. These voltage levels pose a 
potential shock hazard to the user. Do not touch test lead tips or the circuit being tested 
while power is applied to the circuit being measured. Keep your fingers behind the 
finger guards of the test leads during measurement. Inspect test leads, connectors, and 
probes for damaged insulation or exposed metal before using the instrument. If any 
defects are found, replace them immediately. Do not measure any current that exceeds 
the current rating of the protection fuse. Do not attempt a current measurement to any 
circuit where the open circuit voltage is above the protection fuse voltage rating. 
Suspected open circuit voltage should be checked with voltage functions. Never attempt 
a voltage measurement with the test lead inserted into the 

A/mA or A input jack. Only 

replace the blown fuse with the proper rating as specified in this manual. 
 
CAUTION 
Disconnect the test leads from the test points before changing functions. Always set the 
instrument to the highest range and work downward for an unknown value when using 
manual ranging mode.
