  • Page 46: Introduction To Loop Testers

    3200A SERIES OPERATION MANUAL Introduction to LOOP Testers What is the loop? When an appliance is connected to the mains supply a circuit is made. It completes the loop current flow round the circuit loop from the power station in the live wire through the appliance and then back to the power station in the neutral wire.
  • Page 47 3200A SERIES OPERATION MANUAL It can be seen that the maximum current that could flow would be 230 Amps even if the appliance was a dead short circuit. A fuse or protection device lower than 230 amps would be needed to protect this circuit. It should be noted that some testers take the lowest loop, either live/neutral or live/phase to calculate the PSCC while others will use only the live/earth loop resistance.
  • Page 48 3200A SERIES OPERATION MANUAL What happens on an RCD protected circuit when using a loop tester? As the test current (23A) flows down the earth conductor any current RCD (Residual current breaker) in the circuit will trip out. To test loop impedance on protected circuits the breaker must either be temporally wired out or a loop tester with a no trip range must be used.
  • Page 49 3200A SERIES OPERATION MANUAL IMPORTANT SAFETY WARNING THE FOLLOWING PROCEDURE MAKES CONNECTION DIRECTLY TO MAINS LINE VOLTAGES WHICH ARE UNPROTECTED BY AN RCD BREAKER - THERE IS EXTREME RISK OF ELECTRIC SHOCK UNLESS PROPER SAFETY PRECAUTIONS ARE TAKEN. THIS PROCEDURE MUST ONLY BE PERFORMED BY QUALIFIED ENGINEERS.
  • Page 50 3200A SERIES OPERATION MANUAL When using the 3200A it is important to remember the test socket is the socket at the end of the adapter cable, NOT THE RESISTANCE OF THE SOCKET INTO WHICH THE 3200A IS PLUGGED. The loop value measured at this test socket can then be manually entered into the 3200A which will add this value to the calibrated values.
  • Page 51 3200A SERIES OPERATION MANUAL The lowest value will be obtained near where the supply enters the building. Remember every switch, fuse socket; even the 3200A will add resistance. If it is required to calibrate at values below that available from of the 3200A then a short length of extension cable of which the resistance of the live + earth conductors have been measured by a 4 wire DMM can be used.
  • Page 52: Calibrating Loop Testers Using The 3200A

    3200A SERIES OPERATION MANUAL Calibrating LOOP Testers using the 3200A Loop testing using the 3200A is performed using a fixed set of resistance ranges, with auto (optional extra) and manual loop measurement. Auto Loop Measurement NOTE: Auto loop measurement is an option specified when a 3200A is ordered.
  • Page 53 3200A SERIES OPERATION MANUAL Use the socket marked Loop & RCD Testers to perform RCD tests. When the TEST soft key is pressed on the 3200A front panel, the 3200A pre-tests the LOOP tester to detect faulty devices. Should a faulty device be detected the output will be automatically switched off and a fault message will be displayed on the 3200A display.
