SAFETY INFORMATION 

WARNING 

Denotes a potentially hazardous situation that may result in injury or death 

CAUTION 

Denotes a potentially hazardous situation that may result in damage to the meter 

NOTE   

Denotes a situation that may result in degraded or incorrect measurement 

 

Use caution in the operation of this device.  Improper use 
may result in injury or death. Read this user manual before 
operating the meter. 

 

Always remove leads before opening the case. 

 

Do not operate the meter unless it is fully assembled with 
both case screws tight. 

 

Only use appropriately rated fuses. 

 

Always check for damage before use.  Pay special attention to 
the test leads for signs of damaged insulation or exposed 
conductors.  Immediately replace damaged leads. 

 

Only use test leads that are rated to at least CAT III 600V. 

 

Keep fingers behind the guards on the leads. 

 

Use caution working with voltages above 30VAC rms, 42VAC 
peak, or 60VDC. Voltages this high pose risk of shock. 

 

Never apply more than 600V between any terminal and earth 
ground. 

 

Do not apply more than 2.0V to the auxiliary terminal with 
respect to Common.  Doing so may draw unexpected current 
and trigger protection circuits.  In this event, basic 
functionality will automatically return within one minute.  
Accuracy may be adversely affected for up to five minutes.   

 

Error messages may appear on the user interface.  Read 
these messages for further information. 

TABLE 1 SYMBOLS 

 

Caution: Risk of Electric Shock.  Refer to operating instructions. 

 

Important Information: Refer to operating instructions. 

CAT III 

This instrument is rated for installation category III per IEC 61010. 

 

Double Insulation 

 

Terminal protected by fuse.  Current limit of 10A RMS. 

 

Conforms to European Union Directives 

 

Do not exceed 600V with respect to ground.
