- Please store the lithium battery LS14250 in a place that is 20℃ or less.

- When using lithium batteries other than LS14250 produced by SAFT, such as

CR2, product specifications cannot be guaranteed nor can the performance of

some functions, such as the battery warning function.

- Please avoid using the CR2 in the following situations:

Using the unit in an environment below

0℃ or above 60℃

Exposing the CR2 to continuous vibration such as in transportation

- When using a CR2 lithium battery, the tube is not necessary.

- To maintain waterproof capacity, when changing batteries also change the

rubber packing and the drying agent (silica gel). When using a CR2 lithium

battery, please purchase the optional Maintenance Set (TR-00P1) to replace

Cautions about the Temperature Sensor

When using the included Sensor TR-5106, please take note of the following:

Do not bend or press the last 5 cm to the tip of the sensor, as this may
damage it.

This may cause trouble or break the wire.

If the fluoropolymer-coated section of the sensor and/or the cable has a
defect or tear, the waterproof capacity will be lost.

Inspect it before operation.

Insert the sensor tip to about 5cm or more to obtain on accurate temperature
measurement.

Only use the sensor within the sensor temperature durability range.

Notes about Communication Devices

-When using a Data Collector, you can download recorded data, view the
data in graph form, and make all necessary recording settings without
connecting to a PC.

-

The time necessary to download one Unit of full data varies depending

upon the type of device being used.

Communication with your Computer

In order to change settings in the Unit such as recording settings, download recorded data from the Unit to your computer, or communicate with your computer, it

is necessary to purchase separately a Communication Port or Data Collector.

By using the Software "T&D Recorder for Windows” supplied with the Communication Port or Data Collector, it is possible to carry out communication
with a PC. For details about how to make recording settings, download data and other operations, please see the User’s Manual that comes with the
Communication Port or Data Collector.

The latest version of “T&D Recorder for Windows” can be downloaded free of charge from our Web Site. (TR-51i and TR-52i can be operated with the Software
version 1.80E or later.)

-This Unit is an infrared-equipped device. Do not place the Unit in areas exposed to direct
sunlight, directly below an incandescent lamp, or near other infrared devices.
Placing in such an area may cause infrared commun

ication to not work properly.

-Also, Infrared communication may not be carried out properly in a
low-temperature environment (below -20℃).

-Proper communication may not be possible if the infrared port is dirty.

-During the infrared communication, do not touch the infrared port or
interrupt the communication.

-Before replacing a battery, please make sure to download any necessary data and proceed
with changing the battery.

-Downloading of data cannot occur while the battery is removed.

Cautions for Using in a Low-temperature Environment below -20℃

-When using in an environment below -20℃, the battery life will be halved.If the battery life

has depleted to half or less under normal conditions and then is moved to an environment
of –20℃ or less, the battery warning mark will come on and in abo

ut one day’s time the
battery may lose all power. If you use the Unit in a low-temperature environment, we
suggest replacing the battery as early as possible.

Battery Replacement Mark

1.

When it is time for the battery to be replaced, a battery life
warning signal will appear.

Please replace the battery as soon as possible if this mark appears.

2.

After removing the battery, wait for about three seconds
until the “bAtt” mark appears. Once this appears, please
insert the new battery as quickly as

possible.

-If the battery is replaced before the “bAtt” mark appears, the
battery life warning signal may remain even after replacing.

-If you change the battery at this point, all recorded data will be saved.

3.

If the battery is further left unchanged, the display will
automatically shut off.

If, at this time, a new battery is placed in the Unit, the “CHEC” mark will
appear on the display after which recording will begin again using the
previously set recording conditions. Note however that all previously
recorded data will have been lost.

Estimating Battery Life

The battery-life warning signal will appear based upon the calculation of
battery use. This mark may not appear correctly if the same battery is taken
out and put in, therefore do not remove the battery until it can be replaced
with a new one. If infrared communication is set to be permitted, battery life
will be shortened.

Unit with the warning LED blinking, measuring in an environment below -20℃ , or
leaving the Unit unconnected to the sensor for several months (TR-52i).

Other Messages

If this appears, all data that was stored in the Unit

will have been erased.

This will be displayed under the following
conditions:

- The first time a battery was inserted after purchase

- If the battery is replaced after having been taken out
for a long period

- If the battery is replaced after the battery power has
been lost.

Warning (set limit exceeded)

Warning LED (flashes)

Using the Software that comes with the

Communication Port or Data Collector, you can

make settings for the Upper / Lower Limits and

Judgment Time. If a measurement exceeds one

of the set limits, the warning LED and a message

will be displayed.

[Upper Limit Exceeded]

If a measured temperature exceeds the set
upper limit, the Logger LED will alternately flash
between [Hi] and the measurement.

[

Lower Limit Exceeded]

If a measured temperature exceeds the set
lower limit, the Logger LED will alternately flash
between [Lo] and the measurement.

Starting the Warning Monitoring Function

If these settings are made in an environment where one of the limits is
being exceeded and recording is started, the monitoring function will enter

“

wait” mode. Once a measurement returns to within the set limits, the

monitoring function will begin to operate.

How to Turn Off a Warning

-Restart recording from the software.

-Use [Clear Warning] setting from the software (only via TR-50U).

-Download the recorded data (only when successfully completed).

-Produce a condition so that “CHEC” is displayed. (see [Check] above).

[Measurement Range Exceeded (for TR-52i only)]

The temperature display blinks when the

temperature exceeds the measurement range
(-60℃ or below / 155℃ or above).

[Sensor Unconnected (for TR-52i only)]

This will be displayed when a sensor has not
been connected or the wire has been broken.
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.

Downloading Recorded Data via Infrared Communication

By using a Data Collector TR-57DCi, it is possible to download
the recorded data from a TR-51i /52i via infrared communication.

Note

＞

-

Please note that infrared communication is a function limited to the downloading
of recorded data. Other functions such as making Unit settings cannot be carried

out.

-

For downloading one TR-51i/52i Unit at full storage capacity, it takes about 60

seconds.
