For further information regarding the Socket and See Multifunction Loop Tester, please see the following description.
This device is a multifunction loop tester that can be used to accurately gain measurements of loop, mains voltage, correct wiring and correct polarity.
The DL420’s wiring test can be used to detect missing earth or neutral (>15kΩ), L-E/L-N swaps, live earth-neutral reversal (using a polarity test pad) and has an accuracy of ±1% ±1V when performing phase-neutral, phase-earth voltage and neutral-earth voltage measurements.
Loop testing using the DL420 is performed across three different ranges: 0 to 9.99Ω, 10.00 to 99.9Ω and 100.00 to 500Ω. This mode also uses no-trip technology for 3 wire testing of phase-neutral-earth when they’re all connected. The DL420 also comes with a 2-wire high current mode which includes a range of 0.00 to 9.99Ω.
Additional features of this device include protection against accidental phase to phase connections, instant readout of prospective fault current, accurate mains voltage measurement (in accordance with BS7697), polarity testing for overall system checks and the utilisation of true impedance techniques to enhance PFC measurement accuracy.
