Safety Measures 

 

The GT-600/GT-800 appliance tester has been built and tested in compliance with 
the valid safety regulations and left the factory in safe and perfect condition. In 
order to maintain this condition and to ensure safe instrument operation, the 
user must pay attention to the references and warnings contained within this 
instruction manual. 

 

 WARNING, DANGER OF ELECTRICAL SHOCK  

 

  In order to avoid electrical shock, the valid safety and national regulations 

regarding excessive contact voltages must receive utmost attention when 
working with voltages exceeding 120V DC or 50V RMS AC. 

  The respective accident prevention regulations established by the national 

health & safety board for electrical systems and equipment must be strictly 
met at all times. 

  Prior to any operation, ensure that the instrument, test leads, mains cable 

and accessories are in perfect condition. 

  The instrument may only be connected to mains voltage as indicated in the 

technical specification section. 

  The instrument may only be used within the operating ranges as specified in 

the technical specification section. 

  Only touch test leads and test probes at handle area provided. Never directly 

touch test probes. Direct contact to measurement connectors or test probes 
must be avoided at any time. 

  The instrument may only be used in dry and clean environments. Dirt and 

humidity reduce insulation resistance and may lead to electrical shocks, in 
particular for high voltages. 

  Never use the instrument in precipitation such as dew or rain. In case of 

condensation due to temperature jumps, the instrument may not be used. 

  A perfect display of measurement values may only be ensured within the 

temperature range of 0 °C to +40 °C. 

  Prior to opening the instrument ensure that it is switched off and 

disconnected from all current circuits. 

  To ensure a safe measurement only use original test leads and accessories. 
  If the operator’s safety is no longer guaranteed, the instrument is to be put 

out of service and protected against use. The safety can no longer be 
guaranteed if the instrument (or test leads):  
– shows obvious damage 
– does not carry out the desired measurements 
– has been stored for too long under unfavourable conditions 
– has been subjected to mechanical stress during transport. 

  Dangerous voltages may be present on appliances or device under test (DUT) 

caused by insulation test. Do not touch the appliances under test, danger of 
electrical shock! 

  Start any test series by protective bonding resistance measurement. 
  At protective bonding resistance test, insulation test and substitute leakage 

test, unit under test must be voltage-free. If necessary check the unit is 
voltage-free i.e. by using a voltage tester. 

  Accidental measurement of a defective unit may trip an RCD (residual 

current device).
