Safety 

This symbol adjacent to another symbol, terminal or operating device indicates 

that the operator must refer to an explanation in the Operating Instructions to 

avoid personal injury or damage to the meter.

This WARNING symbol indicates a potentially hazardous situation, which if not 

avoided, could result in death or serious injury.

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) so marked must not connected 

to a circuit point at which the voltage with respect to earth ground exceeds (in 

this case) 1000 VAC or VDC.

This symbol adjacent to one or more terminals identifies them as being associ-

ated 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.

This symbol indicates that a device is protected throughout by double insulation 

or reinforced insulation.

Safety Instructions

This meter has been designed for safe use, but must be operated with caution. The rules 

listed below must be carefully followed for safe operation.
•  NEVER apply voltage or current to the meter that exceeds the specified maximum:

•  USE EXTREME CAUTION when working with high voltages.
•  DO NOT measure voltage if the voltage on the “COM” input jack exceeds 1000V above 

earth ground.

•  NEVER connect the meter leads across a voltage source while the function switch is in the 

current, resistance, or diode mode. Doing so can damage the meter.

•  ALWAYS discharge filter capacitors in power supplies and disconnect the power when  

making resistance or diode tests.

•  ALWAYS turn off the power and disconnect the test leads before opening the covers to 

replace the fuse or batteries.

•  NEVER operate the meter unless the back cover and the battery and fuse covers are in 

place and fastened securely. If the equipment is used in a manner not  

specified by the manufacturer, the protection provided by the equipment may be impaired.
