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.
