NJTY 3266TA/3266TD Digital Clamp Uputstvo za upotrebu merača

1. Uvod

The NJTY 3266 Series Clamp Meters (models 3266TA and 3266TD) are professional-grade digital multimeters designed for electricians and technicians. These meters offer reliable and accurate measurements for various electrical parameters, featuring True RMS technology for precise readings of complex waveforms up to a 2kHz frequency response. With a 25mm large-diameter clamp head, they can easily accommodate industrial-grade thick cables. Both models include an intelligent safety system with 600V over-voltage protection and Non-Contact Voltage (NCV) detection. The meters are built with a military-grade design, offering IP54 dust and water resistance, and a lightweight body for extended use.

This manual provides detailed instructions for the safe and effective use of your NJTY 3266TA or 3266TD Digital Clamp Mjerač. Molimo vas da ga pažljivo pročitate prije upotrebe.

2. Sigurnosne informacije

Always adhere to basic safety precautions when using this product to reduce the risk of fire, electric shock, or personal injury. This device is dual UL/CETL certified to meet OSHA safety standards.

• Ne prekoračujte maksimalna ulazna ograničenja za bilo koju funkciju mjerenja.
• Budite oprezni kada radite sa voltagiznad 60V DC ili 30V AC RMS, jer predstavljaju opasnost od strujnog udara.
• Provjerite da li je mjerač u ispravnoj funkciji i rasponu za mjerenje.
• Prije upotrebe provjerite mjerne kablove da li ima oštećene izolacije ili izloženog metala.
• Ne koristite mjerač ako izgleda oštećeno ili ako je kućište otvoreno.
• Odmah zamijenite bateriju kada se pojavi indikator slabe baterije kako biste osigurali tačna očitavanja.
• Place your fingers under the curved part of the clamp for safety when measuring current.
• Nemojte clamp two wires with opposite currents together as the currents may cancel each other out, leading to inaccurate readings.
