. Outline of System
To start and stop recording, make or change the various recording settings and/or collect data please see the
following instructions.
For details about how to change settings and about communications please see the User's Manual that comes
with the
RTR-
57
U
or the TR-
50
C. You can also find detailed information in the User's Manual and in the Help
Menu of the software.
Optical Communication with an RTR-
57
U
By simply placing an RTR-
51
/
52
unit face down on an
RTR-
57
U
you can carry out recording start settings and
changes, as well as, collect recorded data via optical communication.
Using Wireless Communication with an RTR-
57
U Unit
By registering an RTR-
51
/
52
unit as a Remote Unit of an
RTR-
57
U
, it is possible to carry out wireless data
communication (special short wave radio) allowing you to start and stop recording, make recording condition
settings and collect data without having to handle the RTR-
51
/
52
units.

. Getting Started
1
.
Remove the screws and take off the back case.
NOTE:
When changing batteries make sure to carefully read [
5
. Changing Batteries].
If nothing appears on the LCD Display, please follow the above instructions again.
Upon first installation of the batteries, measuring and recording will automatically begin at the factory
set default recording settings: (Recording Interval:
10
minutes / Endless Mode / Immediate Start)
After replacing the batteries the settings will return to the most recent recording settings.
3
.
Check the rubber packing for any cuts or scratches and replace the cover as it was when opened.
Make sure no water or foreign objects get inside the case.
If dirt or scratches are present on the rubber packing, water
resistance will be reduced.
Be sure to fasten the cover tightly.
2
.
Insert the battery in its tube and place in unit as in diagram.
Make sure that + and - are correct.
Insert the batteries
This system makes use of the RTR-
51
/
52
unit to measure and record temperature
data, which can then be downloaded via wireless transmission to our handheld
RTR-
57
U
Data Collector Unit. The
RTR-
57
U
Unit can then be connected to your computer
for data analysis and management with our exclusive software.
Besides the collection of recorded data, it is possible to monitor current temperature
readings, start recording and check data anytime without physically collecting
the RTR-
51
/
52
units. Communication between units can be done via optical
communication, as well as wireless communication.
Basic Functions of RTR-
51
/
52
Wireless Communication Function
Via special short wave radio communication recorded data can be downloaded
from an RTR-
51
/
52
unit and saved to the
RTR-
57
U
Data Collector Unit. Recording
settings and recording start can also be controlled via wireless communication.
Wireless Communication can occur between an RTR-
51
/
52
Unit and an RTR-
57
C Unit within a range of up to about
330
ft [
100
meters], if unobstructed and
direct.
Note: In order to collect data via wireless communication, it is necessary to
register via computer the RTR-
51
/
52
unit as a Remote Unit in the
RTR-
57
U
Unit you wish to use. For details about making these settings, please see the
Help Menu in the software or the User's Manual for the software.

Setting the Recording Conditions
Communication with your Computer
By placing an RTR-
51
/
52
unit face down on an
RTR-
57
U
unit that is connected to your computer, you can make
any necessary recording conditions settings and changes, start recording and download recorded data easily
via your computer display.
Place the RTR-
51
/
52
unit
face down on the
RTR-
57
U
If you are going to be using wireless communication
it is necessary to register the [Group Name] and
[Remote Unit Name] information in the RTR-
57
U
units.
The wireless communication range, if unobstructed
and direct, is about
330
ft [
100
meters]. In some
cases communication cannot take place even within
330
ft [
100
meters]. Please check first by carrying
out the wireless communication test with the remote
units.
4
. Connect the Temperature Sensor. (RTR-
52
Only)
Make sure that the sensor is properly connected by inserting it until you hear a clicking sound.
Insert cable into jack
5
. After Inserting the Batteries
If necessary make changes to the default recording settings according to your usage and needs. If
you are going to be using wireless communication it is necessary to register the [Group Name] and
[Remote Unit Name] information at this time. See [
3
. Settings and Communication]
5
. Changing Batteries
NOTE: After removing the old batteries, replace them with new batteries within
1
minute.
1
. When the battery power becomes low, the BAT indicator will appear on the LCD display.
Once the BAT indicator appears please change the battery as soon as possible.
Recording: OK
Wireless Communication: OK
Data Download: OK
The recorded data will remain saved.
If at this time a new battery is placed in the unit, recording will continue.
After changing the battery, the BAT indicator will disappear in a short time.
2
. If you do not change the battery and continue using the unit, the temperature display will intermittently
display {bAtt}. Please change the battery at once.
Recording: OK
Wireless Communication: No
Data Download: No
The recorded data will remain saved.
If at this time a new battery is placed in the unit, recording will continue and downloading of saved data can be done.
After changing the battery, the temperature display will return to displaying only the temperature after which the BAT indicator
will disappear a short time later.
3
. If you do not change the battery even under conditions in
2
above, the REC indicator will disappear and
temperature display area will display [SLP]. ("SLP" stands for "Sleep Mode".)
Recording: No
Wireless Communication: No
Data Download: No
Recording will stop and recorded data until this point will be saved.
If at this time a new battery is placed in the unit, downloading of saved data can be done. To start recording again please set the
recording conditions via your computer or
RTR-
57
U
and begin recording. See [
1
. Outline of System]
After changing the battery, the temperature display will return to displaying the temperature.
4
. If you do not change the battery even under conditions in
3
above, the display will go blank.
All of the recorded data will be erased.
If at this time a new battery is placed in the unit, [CHEC] will appear on the display after which recording will begin again using
the previously set recording conditions.
The recording conditions include [Recording Mode], [Recording Interval], [Start
Recording Date and Time] and [Unit of Temperature]. Detailed instructions on
how to change these settings are provided in the User's Manual for either the
RTR-
57
U
or TR-
50
C.
Recording Mode: Select from two types of Recording Mode
ONE-TIME MODE:When the data capacity of
16
,
000
readings is reached,
the LCD display will indicate [FULL] and recording will stop.
ENDLESS MODE: When the data capacity of
16
,
000
readings is reached,
the data will be erased in order from the oldest data first and recording will
continue.
*Below is an estimate of the amount of time it will take for the unit to
become [FULL] in the ONE-TIME MODE.
Calculation Example:

Check
This is displayed under the following conditions: after purchasing and putting
in the batteries for the first time, if the battery ter/- were mistaken and
a short occurred, or if the batteries are replaced after having been taken out
for a long period. If this is displayed, all data that had been stored in the main
unit has been erased.
Full Memory
If recording under the ONE-TIME MODE, when the data readings reach the
upper limit of
16
,
000
readings, recording will stop and this will be displayed
intermittently with the current temperature.
Wireless Transmission
This will be displayed when transmitting data to an
RTR-
57
U
unit via wireless
communication.
No Sensor Connected (Only for RTR-
52
)
Displayed when a sensor has not been connected or the wire has been
broken. Measurement and recording will continue and battery power
consumed.
Measurement Over Range (Only for RTR-
52
)
The current temperature display will blink when the temperature exceeds
-
76
F
or +
