It also blinks if, when using range hold, the value exceeds
the range upper limit.
Always note the measurable values of each range
Underrange Error
The display blinks if the measured optical power level falls
below the minimum measurable value.
It also blinks if, when using range hold, the value falls below
the range lower limit.
Always note the measurable values of each range.
