Important Information

These operating instructions are intended for the use of adequately trained personnel.
Before use, ensure that the live line tester is clean and dry; visually inspect all parts. Any damage must be rectified prior to use.
Never hold a Live Line Tester between the hand-guard and the contact electrode.
Always prove the Live Line Tester before AND after use.

  1. Holding the live line tester by the handles, above the handguards, connect the instrument to a Seaward PH3-LLT proving unit and verify that the LED indicators are illuminated.

  2.  Reverse the connections to the PH3-LLT and repeat step 1. This proves the LLT in both polarities.

  3.  Holding the live line tester by the handle, above the handguards, place the contact electrodes in contact with the circuit under test.

  4.  If the LED indicators are illuminated there is a voltage greater than the threshold voltage present at the probe tips.

  5. If the LED indicators do not illuminate, replace PP3 9V battery inside PH3 and repeat step 1 and 2. If LED indicators do not illuminate still, this suggests LLT is faulty and should NOT be used. Contact the manufacturer or an authorised Seaward Service
    Agent for advice.

  6. Repeat step 1 and 2 above to verify that the instrument is still operational.
