The clock will initially show Minutes : Seconds, and then Hours : Minutes after one minute has passed.
After 1 day the 24 hour timer resets to 0 and ’1′ is added to the Day counter. To see the total appliance run-time go to the ‘kWh’ screen where total Days are displayed in addition to the 24 hour timer. For example, after 55 hours of an appliance using more than 0 watts it will read 2 Day and 07:00.
