Funkcionalnost
Merilniki delujejo lahko kot dataloggerji ali pa direktno pošiljajo podatke spejemni enoti prek kratkih radijskih valov - brezžično. Njihov domet je 150 m, za podaljšanje pa lahko uporabimo repetitor. Prenos podatkov je samodejen glede na nastavitve oz. ko je sprejemik v dosegu. Merilniki RTR-574 imajo 8.000 spominskih točk! Merijo temperaturo, relativno vlago, osvetljenost in UV intezivnost.
Download Data via Wireless Communication with a Base Unit
Recorded data can be downloaded from RTR-501/502/503/574 Data Loggers (Remote Units) via wireless communication with a Base Unit.The wireless communication range between a Remote Unit and a Base Unit is about 150 meters [500 ft].By registering an RTR-500 as a Repeater, it can be used to expand the wireless communication range.
Low Energy Consumption Design
The RTR-574 uses one AA alkaline battery. If one Unit of full data is downloaded once a day via wireless communication, the estimated battery life will be about four months. (There is no L-type model for RTR-574)
The buttons on the face of the RTR-574 Unit make it possible to change the LCD display pattern, start and stop recording, make or change recording interval settings, and turn power ON or OFF.
To prevent unexpected errors in button operation, you can use the software supplied with the Base Unit to lock the button operation.

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".
