  • Page 8: Voltage Measurement

    4-1 Voltage Measurement When the Loop and PSC Testers are first powered up by connecting them to the mains, they automatically display the mains voltage. The voltage display is updated automatically every 0.5s. When the test button is depressed (see section 5.1 first) the voltage mode is cancelled.

  • Page 9: Operating Instructions

    OPERATING INSTRUCTIONS 5-1 Correct Wiring Before pressing the “Test Button” always check the P-E, P-N, neon lamps for the following light sequence : P-E Neon must be ON P-N Neon must be ON Neon must be OFF If the sequence of lights is not as above DO NOT PROCEED with further testing.

    Press the “Press to Test” button. The value of loop impedance will be displayed with the appropriate units. A bleep will sound on completion of the test. For best results always test on the lowest possible range. No harm will be done to the instrument by selecting too low a range.

  • Page 11: Measurement Of Prospective Short Circuit Current

    5-4 Measurement of Prospective Short Circuit Current Note : There units are only intended for single phase operation. Set the instrument to the 20kA range. Connect the test lead to the instrument. Attach the plug to the socket to be tested. Check that the neons are lit in the sequence indicated in section 5-1.
