■ circuit resistance tester features
▲ the test current is large, which fully meets the standard requirements for testing contact resistance.
▲ high output voltage, wide measuring range, up to 100m Ω.
▲ the test current comes from the high-precision switching constant current power supply, which does not need manual adjustment, and the test is fast and accurate.
▲ the four terminal wiring method is adopted to effectively eliminate the influence of the test line resistance on the test results.
▲ the test speed is fast, and the data is displayed in about 3 seconds.
▲ it works continuously for a long time, with overheating protection circuit, and the instrument is reliable and stable.
▲ simple operation and light weight, suitable for field operation.
