Operation Terminology


The false appearance of a positive resistive voltage (negative resistance) is the result of the Quench Protection Monitor's calculation during an actual quench in another cell or due to an instrumentation failure. The antiquench applies only to positive resistive voltage readings that exceed the antiquench limit of +3 volts and fire the heaters. The small positive excursions seen when adjacent cells quench are not antiquenches.
