Application:
It is suitable for high-voltage switch contact (loop) resistance high precision test, which is also suitable for other occasions requiring large current and micro resistance measurements. The test current is recommended by the national standard DC 100A and 200A. The loop resistance can be measured directly under DC 100A and 200A condition, and the test results are displayed with a large LCD screen, with data storage, output printing and time setting functions.
Product Features:
1. Large current: using the latest switch power source technology, can continuous output current for a long time to overcome the disadvantages of pulse power supply relative current , can effectively breakdown the switch contact oxidation film, get good test results.
2. High stability: in the severe interference condition, the last data of the LCD screen can be stable in the range of plus or minus 1 letter, stable reading and good repeatability.
3.High precision: the two-way high-speed 16-bit Σ - Δ AD sampling, use latest digital signal processing technology, the highest resolution is 0.01 mu Ω, is currently the unique contact resistance tester can reach 0.01 mu Ω resolution and very stable at home, performance is better than imported large current microhm meter.
4. Intelligent: import high performance CPU, automatically switch measuring range according to signal size to ensure product test accuracy. The overtemperature protection circuit can automatically stop output current when the instrument exceeds the setting temperature to ensure instrument safely use.
5.High Quality: key components all adopt imported components, through the clever design of temperature compensation circuit effectively eliminate the influence of environment temperature on the measurement results, the use of military connector enhances the seismic performance.
6. Powerful: Freely choose current at 50 A, 100 A, 150 A and 200 A, test time can be arbitrarily set within the 5 s ~ 599 s, overcome other similar instruments can't set measuring time or continuous work time is too short, is far more than the performance of other similar instruments.
7. Friendly man-machine interface: input data by rotating mouse, convenient and fast, can set the instrument date and time, save the measurement data in real time, and print the measurement results immediately.
8. USB transfer: the measurement data can be transferred to USB disk via the USB interface, and further analyzed and processed measurement data by the upper computer software.
9.Convenience: small size, light weight, easy to carry.
