Elapsed Timer with Hold
In this mode, measurements are made while the countdown timer is running. When the timer reaches zero, the last measurement is held on the display
Stray Light Inhibit
This feature allows the user to measure light from one source while automatically factoring out the light from a secondary (stray) unwanted source.
Integral Illuminance Mode
Integral Illuminance is a luminous energy measurement based on the rate of flow of flux (expressed in lumen-seconds). The Model EA33 can also measure any photometric quantity on a time dependent basis. For example, the illuminance could be integrated over time to yield lux-hours (lx-h) or foot candle-hours (fc-h).
