Safety Symbols

This symbol adjacent to another symbol, terminal, or operating 

 

device, indicates that the operator must refer to an explanation 

 

in the Instruction Manual to avoid personal injury or damage to 

 

the meter.

This WARNING symbol indicates a potentially hazardous situation, 
which if not avoided, could result in serious injury or death.

This CAUTION symbol indicates a potentially hazardous situation, 
which if not avoided, may result damage to the product.

This symbol advises the user that the terminal(s), marked as so, 
must not be connected to a circuit point at which the voltage, with 
respect to grounding, exceeds the stated amount of Volts (in this 
case 500 VAC or VDC).
This symbol, adjacent to one or more terminals, identifies them 
as being associated with ranges that may, in normal use, be 
subjected to particularly hazardous voltages. For maximum safety, 

the meter and its test leads should not be handled when these 

terminals are energized.
