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).
