4. Battery Replacement Mark
When the replacement mark [
] appears, try to replace
the battery with a new one as soon as possible.
1. When it is time for the battery to be
replaced, the [
] mark will appear.
2. If you do not change the battery
and continue using the unit, the
temperature display will intermittently
display [bAtt].
- After this point the downloading of data can no longer be done
via wireless communication.
- Without changing the battery and attempting to use optical
communication to download data, the communication may be
broken and if so all recorded data may be lost.
- If the battery is changed at this point, recording will continue after
it has been changed.
3. If the battery is further left unchanged,
the display will automatically shut off.
If, at this time, the battery is changed,
[CHEC] will appear in the display
after which recording will begin again
using the previously set recording
conditions.
* All of the recorded data up until that point will be erased.
The estimated battery life is one year if the wireless communication
interval is 10minutes or longer. If the wireless communication
interval is less than 10 minutes or if the recording interval is set at
10 seconds or less battery life will be shortened.
5. Communicating with a PC
To register a data logger as a Remote Unit connect the data
logger to the computer. For details about how to connect the
unit, see the Introductory Guide that comes with the Base
Unit or see the application’s Help.
Base Unit
- Communication errors may occur in environments where temperatures
are very high or very low.
- If the battery level of the data logger is very low, communication may be
broken or may not be possible.

2. Connecting a Sensor
Make sure that the sensor or sensor adaptor is inserted until
you hear a “click” sound.
About Sensors for RTR-502Pt
Pt100 and Pt1000 sensors are not included in the package with the
RTR-502Pt. Please purchase separately.
1. Loosen the screws on the terminal block of the sensor
adaptor.
2. Connect the sensor terminals to the terminal block as
instructed in the diagram on the terminal block.
3. Securely tighten the screws on the terminal block.

3. Installing the Battery
When a battery is installed, temperature measurement will
start at the factory default settings or the previously set
ones.
Factory Default Settings
Recording Mode: Endless
Recording Interval: 10 minutes
Recording Start: Immediate Start
1. Remove the screws and open the case.
2. Insert the battery into the tube and install as shown in the
diagram.
3. Check the rubber packing for any cuts or scratches and
replace the cover as it was when opened.

(Inserted into tube)
* Make sure to use the proper size and type of screwdriver. A Phillips #1
head screwdriver is best.
* If using a CR2 lithium battery the tube is not necessary.
* If dirt or scratches are present on the rubber packing, water resistance
will be reduced.
* Be sure to completely close the cover. Make sure not to over tighten the
screws.
Appropriate torque: 20N*cm ~ 30N*cm [2Kgf*cm ~ 3Kgf*cm]
Notes about Battery Installation
If a new battery has been installed and recording does not immediately
start, nothing appears in the display or any other such malfunction,
please remove the battery, check to make sure plus and minus are
correct and re-insert the battery.
After inserting the battery for the first time, nothing may appear or
occur for about 10 seconds; this is not a malfunction.
If + (plus) and – (minus) are mistaken, or if the battery terminals + and
– are shorted, the recorded data that is stored in the logger will be lost.
Make sure no water or foreign objects get inside the case.
To maintain water resistibility when changing batteries we suggest also
changing the rubber packing and the drying agent.
About Lithium Batteries
Lithium batteries (CR2) sold in stores may also be used, but if you are
using in an environment below -20
o
C, above 60
o
C, or in a situation
such as transportation where continued vibration is likely to occur,
we strongly suggest the purchase and use of the our lithium battery
LS14250. (Please purchase optional part 11P2)
When using an LS14250 type lithium battery, even though a new
battery has been inserted the BAT indicator may remain on for a short
time.This is due to a special characteristic of the battery. Note that the
longer the battery has been in storage the longer the amount of time,
from 10 minutes to about 1 hour, the BAT indicator will remain on. If
during that time the Base Unit is used to get the Current Status of the
Remote Unit, the remaining battery level will show that the battery
level is low.
Please store the Lithium Battery LS14250 in a place that is 20
o
C or
less.

What is a Wireless Thermo Recorder?
These products are data loggers designed to measure
and record temperature and humidity with built-in wireless
communication capability.
No longer it is necessary to manually gather the data loggers.
Rather via our special short-range wireless communication
function, data download, settings, analysis and the saving of
data can all be done via a wireless Base Unit connected to
your PC.

We have prepared an array of Remote Units to meet
your needs: RTR-501/502/503/502Pt. These Remote Units
cannot be used without a Base Unit. Base Units must be
purchased separately.
