Portable Automatic Loop Contact Resistance High Voltage Switch Testing Equipment
Production Introduction & Features:
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.
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 co mpensation 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.
