NR4200 series cable identification instrument
NR4200 series cable identification instrument is a special instrument used to identify a specific cable from a bunch of cables in power cable erection, migration maintenance and troubleshooting. When identifying a specific cable, it not only uses the current direction as the standard, but also uses the current amplitude value as the judgment standard. This double judgment standard is more likely to identify the cable reliably and accurately. The instrument is a miniaturized portable and compact device, housed in an aluminum alloy box, composed of a generator, a receiver with a caliper, and cables.
◆ The instrument consists of two parts: a signal generator and a signal receiver;
◆ The test current is directly displayed by the meter, which is more convenient and intuitive;
◆ The test voltage and polarity are displayed by the pointer type meter, which is faster, clearer and more convenient;
◆ The instrument is small in size, light in weight, and exquisite in appearance, which is convenient for on-site use;
◆ Adopt the latest working principle to make the test easier.
◆ Power supply for the instrument: The host of the cable identification instrument is powered by AC 220V, and the receiver is powered by a 9V battery;
◆ Caliper: The caliper is a current exchanger, the size of the inner mouth of the jaw is 120mm, the voltage is induced in the caliper, the voltage amplitude is determined by the current intensity, and its polarity is determined by the current direction;
◆ Host size: 400mm*270mm*210mm
◆ Receiver dimensions: 150mm*205mm*50mm
