The ISO 5000 is an electronic insulation resistance tester with a resistance range of 500 k to 500G and an analogue indication. The instrument is engineered to measure and analyze the insulation resistance and safety of motors, machines, ground cables, transformers etc. The tester also measures AC and DC voltage up to 600 V. The logarithmic scale clearly indicates the value. During the development of the tester, the engineers paid special attention to the safety standards (IEC1010) and the requirements of the user. Under normal circumstances, 2.500 measurements can be performed on a stand-alone base.
