In order to download data via wireless communication, it is necessary to purchase Base Unit. |
(*1) When using RTR-500B1 it is necessary to purchase Lithium Battery (LS26500). For details, contact your local authorized distributor.
(*2) The stated battery life is for when it is used in an environment of 25¢ªC (77¢ªF) and recorded data is downloaded at a rate of once a day or "Monitoring Current Readings" occurs at a rate of once every 10 minutes. Battery life depends on measurement environment, recording interval and battery performance.
(*3)The same amount of time will be necessary for each added Repeater.
(*4) The stated water resistance rating is for when the sensor is connected to the unit. However, this does not include the sensor areas for the RTR-503/503L models. Not for continued immersion. |
