Sometimes the event log record for a setting change does not include enough information to identify the actual setting that was changed. For example, an event that reads Time Mult 1.00 identifies that a Time Multiplier setting for a particular protection curve was changed to 1.00. Pressing the EVENT LOG key when that setting change event was displayed may reveal for instance that it refers to the Group A, Trip 1 Phase Protection curve. (A:PH:T1)
