thoroughly before use.

Overview

RTR505B is a data logger designed to measure and record 

different items depending on the input module to be con

-

nected:  temperature (Thermocouple, Pt), analog signal 

(4-20mA, DC voltage), and pulse.

Recorded data is then automatically collected by the Base Unit via 

wireless communication and downloaded for archive and analysis.

RTR505B requires a Base Unit to carry out wireless 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 Data Recorder RTR505B is referred to as the “(data) logger” 

or “device” in this manual.

• Before using the pulse input cable, it is necessary to set the measurement item to “pulse 

type” in the Remote Unit Settings of the application.

• In order to change the measurement item,  initialize the Remote Unit without connecting 

the input module and then redo the Remote Unit registration and settings.

Make sure that the module is completely 

inserted until you hear a “click” sound.

Battery Installation

Recording starts automatically by inserting the battery with the 

default or previous settings.

Recording Start 

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.
