Overview
The RTR501B, RTR502B, RTR503B and RTR507B are wireless
data loggers designed to measure and record temperature
and humidity.
Recorded data is then automatically collected by the Base Unit
via wireless communication and downloaded for archive and
analysis.
RTR501B / 502B / 503B / 507B require a Base Unit to carry out wire-
less communication.
(Compatible Base Units: RTR500BC, RTR500BW, RTR500BM, RTR-
500MBS-A, RTR-500DC, RTR-500, RTR-500NW/AW)
For the operation and configuration of the Base Unit, refer to
the instruction manual attached to the Base Unit or the RTR500B
Series Help available on T&D Website.
Wireless Thermo Recorder RTR501B / 502B / 503B / 507B is re-
ferred to as the “(data) logger” or “device” in this manual.

Method
Immediate Start
• Make sure to use the proper type and
size screwdriver. (Phillips head #1
screwdriver is recommended.)
• Insert the supplied battery with the
tube attached. When using a CR2 lithi-
um battery, the tube is not necessary.
• Before closing the cover, check the
rubber packing for dust or scratches,
as they can reduce the water resis-
tance of the rubber.
• Be sure to completely close the cover.
Make sure not to over tighten the
screws.
• Appropriate Tightening Torque:
20N·cm to 30N·cm (2Kgf·cm to 3Kgf·cm)
Battery Replacement
When it is time for the battery to be
replaced, a battery warning mark will
appear. Please change the battery as
soon as possible if this mark appears.
If you continue to use the logger without changing the battery, the
current temperature and [bAtt] will be displayed alternately and
wireless communication will stop. (Recording will continue.)
Alternating
Display
• If the battery is further left unchanged, the display will automatically shut
off and all previously recorded data will be lost.
• Although the logger continues to work for a period after the battery has
been removed, leaving the device without a battery until the LCD display
goes blank will cause all recorded data to be lost.
