10. Totalized Intensity of Illumination
(ACC Key)
This function is available on Model 51021.
The meter calculates the totalized intensity of illumination and
integral time.
The maximum totalized intensity of illumination is 9990000000 lx h
(three significant digits), and the maximum integral value is
10000 h. (In unit of hours)
If the comparator function is enabled and the totalized intensity
of illumination reaches a preset value, totalization stops at
this point and the display is held. You can read the integral time
when totalization stopped.
To use the comparator function, set the limit value.
Note
If the battery runs low during long-term totalization, an error may be
introduced in the calculation. To perform long-term totalization,
we recommend that you supply power through USB.
