3. Warnings and Instrument messages 

 
 

3.1 Warnings 

 
In order to reach the highest level of operator’s safety while carrying out various 
measurements and tests using the

 GigaOhm 1kV

, as well as to ensure the test 

equipment remains undamaged, it is necessary to consider the following general 
warnings: 
 

 

If the test equipment is used in a manner not specified in this User Manual, 
the protection provided by the equipment may be impaired! 

 

Do not use the instrument and accessories if any damage is noticed! 

 

In case of blown fuse, follow the instructions in this Instruction Manual to 
replace it! 

 

Service intervention or adjustment procedure is allowed to be carried out 
only by a competent, authorised person! 

 

Consider all generally known precautions in order to avoid risk of electric 
shock while dealing with electrical installations! 

 

Use only standard or optional test accessories supplied by your distributor! 

 

Do not connect test terminals to an external voltage higher than 600 V AC or 
DC in order not to damage the test instrument! 

 

!

 symbol at the instrument means “Read the User Manual with special 

care!” The symbol requires an action! 

 

!

 symbol on LCD indicates an irregular condition of the tested item which 

may present a hazardous live voltage. 

 

Disconnect all test leads and switch power off before opening battery cover! 

 

 symbol means that the instrument output can be higher than 1000V 

during insulation test. Especially take care when measuring capacitive 
loads.
