C.A 6454 Loop Tester The C.A 6456 loop tester combines optimum ease of use with true metrological performance for testing compliancy with the NFC 15-100 standard. Safe and direct connection to mains socket on the equipment being tested. Reliable measurements thanks to automatic permutation of L and N inputs if the conductors are reversed at the socket connection. Automatic measurement of the equipment's voltage and frequency. Resistance and impedance of L-N, L-L and L-PE loops from 0.2 → 4 kΩ. Earth resistance measurements when the equipment is POWERED ON: earth loop and 1P earth with choice of measurement current (high for increased precision or low to avoid tripping). Short-circuit current displayed up to 40 kA by calculation (Uref / ZL-PE). Measurement of current & leakage current using the probe (optional). Programmable alarms, date/time recording of results, direct printing of measurement readings using serial printer and data transfer to PC (transfer software included as standard). Large backlit display / hands-free case. Battery-powered; battery life equivalent to 2000 measurements. Dimensions: 270 x 250 x 180 mm. Weight: 900 g. Comes in shoulder bag with accessory case containing: 1 mains lead, 1 3-wire lead, 3 test probes / 3 crocodile clips, 1 user manual in 5 languages, data transfer application software, 1 communication lead. Standards   Cat III 600 V.

Loop/PSCC Tester Martindale LP2000 A fast and accurate autoranging loop tester, which measures loop and prospective short circuit current (lpsc) of electrical circuits in accordance with the IEE wiring regulations (BS7671).
