FEATURES

Ø It is used to measure the resistance, meter resistance, kilometer resistance, DC resistance of motor, transformer and so on of 1-45mm stranded wire and multi strand cable.

Ø The resolution of the instrument is as high as 10-8 Ω (0.01 μ Ω), which ensures the measurement accuracy of the resistance and conductivity of the metal wire with the diameter as high as Ø 45mm (cross-sectional area as high as 1589mm²).

Ø Equipped with high-precision (± 0.1 ℃) temperature sensor or test fixture with high-precision conductor temperature sensor, the accuracy of automatic temperature compensation in measurement is greatly improved.

Ø It integrates advanced electronic technology, single-chip technology and automatic detection technology, with strong automatic function and simple operation.

Ø Press the key only once, all the measured values can be obtained, without any calculation, suitable for continuous, fast and accurate detection.

Ø AC and battery powered design, suitable for field and field use.

Ø Large screen, large font, which can display the meter resistance, kilometer resistance and other measurement values and temperature, test current, temperature compensation coefficient and other auxiliary parameters at the same time, very intuitive.

Ø Each measurement has the function of automatically selecting the constant current, automatically reversing the current, automatically correcting the zero point, overcoming the error caused by the resistance from the thermal voltage to the line, and ensuring the accuracy of each measurement.

Ø It can adapt to all standard 1 meter test fixtures or non 1 meter test fixtures, and is very flexible to use.

Ø It can be equipped with a series of calibration resistors and related software to facilitate the automatic calibration of the instrument.

Ø It has built-in data memory, which can record and save 1000 groups of measurement data and parameters, and connect the upper computer to generate a complete report.
