If the time-range setting is 
changed, the present 
value will not be held and 
so press the Reset Key on 
the front panel. 

If the time-range switch is set to ”0.0h to 3999d23.9h,” the four leftmost digits are the number of days and the three rightmost 
digits are the number of hours.
The initial value after resetting is 000.00 (0 days, 00.0 hours).
After ”023.9” (0 days, 23.9 hours), the display will change to ”100.0” (1 days, 00.0 hours).
