How long can the overvoltage condition last on the metering inputs of the Series 4000 Circuit Monitor (CM4000)?
Issue
Limits of the CM4000 overvoltage conditions
Product Line
CM4000
Environment
Product Specifications
Cause
Over voltage conditions that the CM4000 can sustain before failure
Resolution
From Table B-1 of Appendix B in the CM4000 reference manual, the meter allows a 50% metering over-range of voltage. The meter can handle this overvoltage condition indefintely.
