ND2671 Digital Insulation Resistance Tester

Product Introduction

        ND2671 Digital Insulation Resistance Tester (also known as Digital Megohmmeter) is composed of large and medium-scale integrated circuits. This instrument features high output power, high short-circuit current value, and multiple output voltage levels (four voltage levels). The working principle involves the internal battery serving as the power source. The DC high voltage generated through DC/DC conversion exits from the E terminal, passes through the device under test to the L terminal, thereby creating a current from E to L. After I/V conversion and processing by the divider, the measured insulation resistance value is directly displayed on the LCD. ND2671 offers output voltage levels of 500V, 1000V, 2000V, and 2500V. It is equipped with an internal equipotential protection ring and a fourth-order active low-pass filter, providing effective isolation against external power frequency and strong electromagnetic fields. It boasts high output power, strong load capacity, and excellent anti-interference capability.

Product Features

☆ High output power, strong load capacity, and excellent anti-interference capability.
☆ The ND2671 Digital Insulation Resistance Tester features a high-strength aluminum alloy casing. It includes an internal equipotential protection ring and a fourth-order active low-pass filter, providing effective isolation against external power frequency and strong electromagnetic fields. For capacitive device measurements, the output short-circuit current exceeding 1.6mA easily allows the test voltage to rapidly rise to the rated output voltage. For low-resistance measurements, the proportional method design ensures that voltage drop does not affect test accuracy.
☆ The ND2671 Digital Insulation Resistance Tester operates on battery power without manual effort and features automatic range conversion. The intuitive panel operation and LCD display make measurements convenient and rapid.
☆ The ND2671 Digital Insulation Resistance Tester allows direct measurement of output short-circuit current without the need for load measurement estimation.
