1. Safety Precautions

Electricity can cause severe injuries even with low voltages 

or currents. Therefore it is extremely important that you read 

the following information before using your analogue insulation 

tester.

1.1  This Instrument must only be used and operated  by a 

competent trained person and in strict accordance with the 

instructions. we will not accept liability for any damage or injury 

caused by misuse or non compliance with instructions and 

safety procedures.

1.2  This instrument must not be used on live circuits.

Ensure all circuits are de-energised before  testing, see 

paragraph 1.8 for details of built-in warning features should 

your analogue insulation tester be connected to a live system.

1.3 Never open your analogue insulation tester except for 

battery replacement. (see battery replacement section) 

1.4  Always inspect you analogue insulation tester and test 

leads before use for any sign of abnormality or damage. 

If any abnormal conditions exist (broken test leads, cracked 

case, display faulty etc...) do not attempt to take any 

measurement or use the tester. Return your analogue insulation 

tester to your nearest distributor for service.

1.5  Never replace the protective fuse with any other 

than the specified or approved equivalent

1.6 Your analogue insulation tester has been  designed with 

your safety in mind. However, no design can completely 

protect against incorrect use.
