RTR-500DC, RTR-500MBS-A, RTR-500NW/AW (*8)(*9)
RTR-500 (*9)
*1: When continually used in environments with temperatures above 60 C, accuracy of humidity measurements will decrease over time. Also, humidity cannot be measured at temperatures below -20 C.
*2: Only “Endless” is available when using the RTR500BW, RTR500BM, RTR-500NW/AW or RTR-500MBS-A as a Base Unit.
*3: Bluetooth is available when using the RTR500BW or RTR500BM as a Base Unit and making device settings in the mobile app (T&D 500B Utility).
*4: When using RTR-500B1 it is necessary to purchase Lithium Battery (LS26500). For details, contact your local authorized distributor.
*5: RTR-500A2 should not be used with the RTR501B, as it will cause the RTR-501 to display a higher than actual temperature reading of up to 3°C.
*6: The listed battery life is based on the following usage conditions: Recording at 10 second (or longer) intervals, Current Readings Transmission every 10 minutes, and Recorded Data Trans-
mission once a day. Battery life also varies depending on ambient temperature, radio environment, frequency of communication, etc.
*7: This is the waterproof capacity of the data logger with the sensor connected. Note that the temperature-humidity sensor is not water resistant.
*8: A rmware update is required to a RTR500B series compatible version.
*9: A software update is required to a RTR500B series compatible version.

How to Read the LCD Display
When being used in very hot or cold environments the display may become dicult to read. This is not a malfunction.
[REC] Mark Shows the recording status.
ON: Recording in progress
BLINKING: Waiting for programmed start
OFF: Recording stopped
[ONETIME] Mark Shows the recording mode.
ON: One Time
OFF: Endless
Battery Warning Mark
Indicates it is time for the battery to be replaced.
Measurement /
Message Area
Measurements or operational messages are shown
here.
When Recording Mode has been set to “One Time” and
the logger reaches its logging capacity, recording will
automatically stop and in the LCD the measurement
and the word [FULL] will alternately appear.
The measurement and the word [SEnd] will alternately
appear when data is being sent via wireless communi-
cation to the Base Unit. Recording will continue during
wireless transmission.
[Ir] Mark
Indicates that the logger (Remote Unit) has not been
registered to the Base Unit or the wireless communi-
cation is stopped (inactive radio).
[COM] Mark
Indicates that the device is in Bluetooth communication.
Unit of Measurement
