Safety measures for 300A contact resistance tester
1. Those who operate a 300A contact resistance tester should have general knowledge of using electrical equipment or instruments.
2. Before using this instrument, it is necessary to carefully read the user manual.
3. The adjustment and maintenance of the instrument must be carried out by personnel and should not be handled by oneself.
4. The instrument should avoid severe vibration, high temperatures, and direct sunlight.
5. This instrument is designed for measuring pure resistance circuits and cannot measure inductive circuits.
6. The test line cannot be removed during testing.
7. The instrument grounding wire must be properly connected
Performance characteristics of 300A contact resistance tester
1. The testing current is high and meets the standard requirements for testing contact resistance.
2. The testing current comes from a high-precision 100A/200A/300A switch type constant current power supply, without the need for manual adjustment, and the testing is fast and accurate.
3. The use of four terminal wiring method effectively eliminates the influence of test wire resistance on the test results.
4. Fast testing speed.
5. Long term operation, equipped with overheat protection circuit, the instrument is reliable and stable.
6. Easy to operate and lightweight.
