|Recording Intervals||Select from 15 choices:
1, 2, 5, 10, 15, 20 and 30 seconds /1, 2, 5, 10, 15, 20, 30 and 60 minutes
|Storage Capacity||Up to 8,000 readings (One reading is a set of data which includes Illuminance, UV Intensity, Temperature, and Humidity measurements.)|
|Recording Mode||Endless : Upon reaching storage capacity, the oldest data is overwritten and recording continues.
One-time: Upon reaching storage capacity, recording will automatically stop.
* When using RTR-500NW or RTR-500AW as a Base Unit, only “Endless” can be selected.
* When using an RTR-500 as a Base Unit, possible to select from either “Endless” or “One-time".

| (*1) Compared to the value measured by the T&D standard sensor for calibration under our calibration light source.
(*2) Up to four digits are valid for the Current Readings and Cumulative Measurements.
(*3) The same amount of time will be necessary for each added Repeater.
(*4)Battery life varies depending upon the measuring environment, the communication frequency, and the quality of the battery being used.
