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).
