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.
-
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.
-
Reverse the connections to the PH3-LLT and repeat step 1. This proves the LLT in both polarities.
-
Holding the live line tester by the handle, above the handguards, place the contact electrodes in contact with the circuit under test.
-
If the LED indicators are illuminated there is a voltage greater than the threshold voltage present at the probe tips.
-
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. -
Repeat step 1 and 2 above to verify that the instrument is still operational.
