- At present, the SA380-IT measures the degree of isolation between circuit circuits as a standing voltage between the two circuits being measured. A table (at the end of this document) must be utilised to determine the possible level of insulation resistance.
- Connecting both B12 and XB12 circuits in the standard arrangement adds the ability to monitor nominal circuit voltage and isolation from earth. This is important as a low nominal circuit voltage may mask an inter-circuit isolation fault due to lower than expected standing voltages.
