   Using Instruction:

1. Used for monitoring imperfect grounding in marine power system;

2. Used for continuos monitor less 500V  insulation resistance between vessel and electric circuit, and alarm release once insulation resistance lower than preset value;

3. Valid Measuring range: 0.005-5MΩ, alarm level: 0.01MΩ,0.03MΩ,0.06MΩ,0.1MΩ;

4. Signal output capacity: DC24V/3A or AC220V/(max)1A, 4 & 5: normal open; 5 & 6 normal close;

5. In the same power system network, it is forbidden to measure insulation resistance by 2 units meter or other instruments.

6. Measuring range: 0-5Ω, rated voltage: AC220V/380V, can customized.
