200A contact resistance tester XHHL3200SC Product Description The loop resistance tester, also known as the micro-ohmmeter and
contact resistance tester, is an instrument developed by our
company for measuring various high-voltage switches, high-voltage
circuit breakers, metal welding components, metal conductor loop
resistance, and precision micro-ohm resistance.
1. This instrument has a built-in large-capacity rechargeable
lithium battery to generate ripple-free DC current, with a maximum
output of 220A. The output current can be fine-tuned in 2.5A steps,
with up to 87 current gears, which can meet the test of multiple
current gears;
2. At the same time, the time (10s, 20s, 30s, 40s, 50s, 60s) can be
set to continuously output large current tests, and high-precision,
high-stability, and high-intelligence tests can still be performed
in a strong interference environment;
3. It has open circuit protection, overheating protection and other
functions.
4. The instrument uses a 5.6-inch color LCD display and an English
operation interface.
5. The standard resistance of the system can be self-checked before
the formal test to ensure accuracy.
6. Wide range, large data storage capacity, strong
anti-interference ability, simple operation, handheld, and easy to
carry. An optional printer is also available for data printing. | Function | Contact resistance tests of high-voltage switches and circuit
