  • Page 24: Working Hours Counter

    Working hours counter The working hours counter detects the time, in which the UMG96L measures and indicates data. The time is measured with a resolution of 15 minutes and is indicated in hours. The work- ing hours counter cannot be deleted. Display example: The UMG96L indicates 40201 working hours.
