 symbol is displayed, the user guide and warnings documentation must be consulted to identify the nature of the hazard and any actions  

 

necessary to avoid the hazard

 

 

Do not use the instrument if there are any signs of damage

 

 

This instrument meets the EMC requirements of Class A applications. Not for use in domestic installations

 

 

All test leads, probes and clips 

must

 be in good order, clean and with no broken or cracked insulation

 

 

Probes and clips should be held behind the finger guard

 

 

Test leads not used during a measurement should be disconnected from the Appliance tester

 

 

During testing, ensure no hazard will exist as a result of normal running or under fault conditions

 

 

During testing the unit under test (appliance) should not be touched, other than using the appropriate accessories, as faulty appliances can present a shock hazard

 

 

Do not touch the exposed parts of test leads during tests as hazardous voltages may be present

 

 

Do not intentionally connect test leads to live systems or hazardous voltages

 

 

Do not touch the IEC extension lead socket pins especially during a test, as hazardous voltages may be present due to a potentially faulty appliance

 

 

Do not touch the exposed earth pins of the 230 V test socket during a test, as voltages may be present due to a potentially faulty appliance

 

 

Serviceable fuses should only be replaced with those that are suitably rated 

 

 

Replacement fuses 

must

 be of the correct rating and type. 

Refer to page 18
