RTR-574 and RTR-576 are data loggers (Remote Units) equipped with wireless communication technology.
The data recorded by a Remote Unit is collected automatically by a Base Unit via wireless communication and then sent to a computer or cloud storage for archive and analysis.
Here is a description of the device. For the settings, refer to the table below [References for Compatible Base Units and Settings].

Press and hold the button until the recording mark () appears or disappears.
The LCD display shows all or selected multiple measurement items in turn. Make settings for the measurement items to be displayed via the software.
The factory default setting is an alternate display between illuminance and UV intensity.
The LCD display shows one measurement item specified by pressing the DISPLAY button.
With each pressing of the button the measurement Item will change; press until the desired item appears.
Switch between fixed display of either temperature or humidity, or alternating temperature and humidity.
With each pressing of the button the display will change; press until the desired item appears.
The factory default setting is an alternate display.
Stop recording first.
By pressing the button for about two seconds, the currently set recording interval will appear on the LCD display.
With each pressing of the button the recording interval time will change; press until the desired time appears.
Resume the recording.
Insert the batteries before turning on the power.
Before turning off the power, stop recording. Even if the power is turned off, the internal data will be retained as long as the battery remains in the unit.
When the RTR-576 is connected to an external power source, the CO2 sensor operates even when the power is turned off, and the light bulb occasionally lights up inside the sensor area.
It is possible to manually calibrate the CO2 sensor by button operation.
Refer to Calibration / Adjustment Function for the method of automatic calibration by software, precautions and operation procedure for manual calibration, etc.
Remove the battery cover and insert the battery, making sure that the + and − are in the correct direction.
Make sure to always use new batteries that have not expired.
For RTR-576: When measuring and recording over long periods of time, please use a supplied AC adaptor.
If running on only batteries, the estimated battery life is about two days. Keeping batteries in the unit allows a backup source of power for when and if electrical power is cut from the AC adaptor.
Leaving alkaline batteries in the unit for a long period of time may cause battery leakage and corrosion. When using as a backup source, we recommend that you change the batteries every few years.
Turn ON the Power.
RTR-574: Press the red POWER button until the LCD display appears.
RTR-576: Turn the POWER switch up to the ON (triangle mark) position.
The recording mark () appears and recording starts automatically. When using for the first time, register the logger as a Remote Unit on the Windows software.
If the batteries are removed when running on battery power only, the unit will start a sixty-second countdown. To continue recording, before the countdown comes to an end, insert new batteries or connect the AC adaptor to supply power.
If power is not supplied, the unit will enter sleep mode.
Connect the supplied sensor to the sensor jack.
For RTR-574: The Illuminance-UV Sensor or the Temperature-Humidity sensor can be connected to either jack.
Cosine Correction Characteristics
Relative Spectral Response Characteristics Graph
ON: Recording in progress.
BLINKING: Waiting for programmed start.
OFF: Recording has been stopped.
At the beginning of every 2,000 readings the scale will be marked from left to right. Logging capacity is 8,000 readings.
Shows communication status but not displayed normally.
ON: The Unit is connected to a PC with the USB cable.
BLINKING: The unit is in wireless, USB or serial communication.
ENDLESS: Upon reaching logging capacity of 8,000 readings, the oldest data is overwritten and recording continues.
ONETIME: Upon reaching logging capacity of 8,000 readings, recording will automatically stop.
The factory default setting is Endless.

When it is time for the battery to be replaced, will appear.
RTR-576
The battery level will be shown in three stages as below. The icon will flash when running on batteries.
OK
Getting Low
Too Low
Includes units of measurement for humidity, temperature, illuminance and UV intensity.
For Illuminance and UV Intensity data, cumulative measurements can also be viewed.
Cumulative Illuminance: lxh、klxh、Mlxh
Cumulative Amount of UV Light: mW/㎠h、W/㎠h
The upper part of the screen displays the current readings of temperature and/or humidity.
The lower part of the screen displays the current readings of CO2 concentration.
After the [/
] stage, if the batteries are not changed but remain in use, the unit will enter sleep mode and stop measurement and recording in order to protect recorded data until this point.
When Recording Mode has been set to "ONETIME" and the Unit reaches its logging capacity of 8,000 readings, recording will automatically stop and in the LCD the current measurement and the word "FULL" will alternately appear.
Stop recording and download the recorded data before resuming the recording.
By setting the "Button Lock" to ON in the Settings Utility or the mobile app, the operational buttons on the unit will be inactive.
If after re-connecting the sensor and measurements can still not be displayed, it is very possible that the sensor or the Unit are defective or have been damaged.
Measurement and recording will continue so battery power will be consumed.
If after re-connecting the sensor and measurements can still not be displayed, it is very possible that the sensor or the Unit are defective or have been damaged.
Measurement and recording will continue so battery power will be consumed.
This appears when power has just been turned ON. If measurements don't appear in the display after waiting for a considerable time, there is a possibility that the sensor is defective or has been damaged. Also, the CO2 sensor will not work if battery power is low.
When the power is turned ON, the logger will display the firmware version for about 2 seconds. You can also check the firmware version on the Windows software.
The JST Connector PAP-04V-S is compatible with the external alarm terminal. For questions concerning sales of the connector, please directly contact JST Mfg. Co., Ltd.

Auto calibration is a function that automatically calibrates the RTR-576 in reference to an assumed outside atmospheric CO2 level of 390 ppm.
Auto-calibration ON/OFF can be changed from the Windows software for your Base Unit - Settings Utility - [Remote Unit Settings].
Upon configuration, you will be prompted to power cycle the RTR-576. (Unplug the AC adaptor and turn off the [POWER] switch, and plug the AC adaptor and turn on [POWER] again.)
The factory default setting is ON.
It enables long-term accurate measurements by gradually adjusting the lowest measured CO2 concentration over a 180 hour period to 390 ppm.
Set to OFF when continuously measuring in an environment where the lowest weekly CO2 concentration differs greatly from the global average concentration of 390 ppm.
For example, set the auto calibration OFF in the following environments:
When auto calibration is set to OFF, the measurement of the CO2 sensor may have a slow drift. To ensure accurate measurement results, periodically place the RTR-576 in fresh air outside and check if the measured CO2 concentration values are close to 390 ppm or not. If not, we recommend that you carry out manual calibration as below.
Turn OFF the [POWER] switch on the unit.
While holding down the [DISPLAY] button, turn on the [POWER] switch.
Keep holding down the [DISPLAY] button until you see [CAL] in the display.
Push the [DISPLAY] button again, and the upper row of the display will show [CAL] while the lower row will show the CO2 concentration.
Wait, without exhaling breath upon the unit until the CO2 concentration becomes stable.
Once the measurement becomes stable, push the [REC/STOP] button.
The display will read [SET] and the calibration process will start (about 1 minute).
The process is complete when the display returns to the measurement value display.
Check to make sure that the CO2 concentration values are close to 390 ppm.
By using Adjustment Tools, it is possible to adjust the readings measured by Remote Units.
Adjustment for differences will be carried out using an adjustment equation of Y=aX+b; where X is the pre-adjusted reading (Current Reading) and Y is the post-adjusted reading.
Use this to adjust all measurements with the same offset. (The whole graph will be adjusted up or down, keeping the same slope.)
Use this to adjust measurements in a wide range or when adjustment cannot be carried out using only one point. (The slope will change.)
