Cautions about using the Sensors

Cautions about using the temperature/humidity sensor TR-3100

The sensor can measure temperature within the range of 0 to 50Ɏ
and humidity within the range of 10 to 95%RH.

Only use the sensor within these ranges.

If extremely severe temperature changes occur, the humidity
measurements may appear abnormal.

Once the sensor's temperature becomes stable, the measurements will
return to normal.

This sensor is not waterproof. Do not get wet.

When measuring with the temperature/humidity sensor in an
environment of 0 to 50Ɏ and less than 30%RH, the measurements
may sometimes fl uctuate. This is not abnormal.

Cautions about using the Sensors

[Handling the temperature/humidity sensor]

- The temperature/humidity sensor should probably be changed after a period of about
one year. After removing the sensor from its package, please change the
temperature/humidity sensor after one year's usage.
During use the temperature/humidity sensor will accumulate impurities (dirt) on the
surface of the sensor is being used in a bad environment (smoky or dusty places) it
may be necessary to change the sensor sooner.

- When the temperature/humidity sensor is not being used, please place it in the
attached vinyl bag with the drying agent included and store it in a cool dark place with
a temperature of between 5 to 25Ɏ and a humidity of below 30%RH.

- Attached to the temperature/humidity sensor are two stickers: a wetness detection
sticker and a temperature detection sticker. If either of the stickers shows abnormality,
you should change the old sensor to a new one immediately.

About Thermo Recorder TR-73U

Outline

TR-73U Thermo Recorder is a data logger capable of measuring, displaying and
recording temperature, humidity, and barometric pressure data. TR-73U has a total of
three channels: one temperature, one humidity, and one barometric pressure channel.
The data recorded into the TR-73U units can then be downloaded quickly via USB
cable to your computer whereby with our exclusive software you can easily process the
data into graphs, tables, save to fi les and/or print it out.
Moreover, it is possible to connect more than one unit at the same time.

Basic Functions

-Barometric Pressure Measuring Rangeȇ750 ȡ 1100hPa

The TR-73U with the internal barometric pressure sensor can measure and record in a
range of 750 to 1100 hPa.

-Temperature Measuring Rangeȇ-40 ȡ 110Ɏ

The TR-73U with the sensor included in this package can measure and record in a
range of 0 to 50Ɏ , but by purchasing one of our optional sensors it is possible to
measure and record in the wider range of -40 to 110Ɏ .
Please take a look at our full range of optional sensors to fi nd one to match your
application.

-Humidity Measuring Rangeȇ10 ȡ 95%RH

The TR-73U with the sensor included in this package can simultaneously measure and
record temperature in a range of 0 to 50Ɏ and humidity in a range of 10 to 95% RH.

-Amount of Recorded Dataȇ8000 readings x 3 channels

One channel can record and hold up to 8000 measurement readings.
At the longest recording interval of 60 minutes, recording can continue consecutively
for 1 year.

-10 Months of Operation with just 1 AA Alkaline Battery

Our low energy consumption design gives you ten months of continuous operation
with only one AA alkaline battery.
This gives you the freedom to use the data loggers in places where they can be left
alone for long periods of time, such as, in transportation or warehouse.

NOTE:

Battery life varies depending upon the type of battery, the measuring environment, the frequency of
communication, and the ambient temperature in which it is used.

Specifi cations and explanations used in this User's Manual are based on operations carried out with
a new battery and are in no way a guarantee of your actual battery life.

Also, if the recording interval is less than 10 seconds, battery life will be much shorter.

2

-Battery Life Warning Display

When the battery power becomes low, a battery life warning signal will appear in the
unit's LCD display.
If the battery power becomes even lower the unit will automatically go into sleep mode
in order to protect the data.

-15 Recording Intervals

Select from 15 recording intervals (from 1 second to 1 hour) to meet your needs.
Select from 2 Recording Modes
One-time ModeȇWhen the number of recorded readings reaches 8000, [FULL] will
appear in the unit's LCD display and recording will automatically stop.
Endless Mode ȇWhen the number of recorded readings reaches 8000, the oldest data
readings will be overwritten and recording will continue.

-Backup Function

When battery power becomes low, a battery life warning signal will appear in the unit's
LCD display and if the battery power becomes even lower the unit will automatically go
into sleep mode in order to protect the data. In sleep mode all normal operations will
stop and it will become impossible to switch on the power of the main unit.

NOTE:

If the main unit remains in sleep mode for about 1 month without a change of battery,
or if the battery is left out of the unit for more than 2 minutes, all recorded data will
be lost.

-Current Readings Monitoring Display

With our exclusive software, you cannot only monitor the current measurements at a
set interval, but can view those measurements in a continually changing graph.
You can simultaneously display the current measurements and corresponding graphs
for the number of units you have connected.

-Adjustment Function

By entering the adjustment values beforehand with the provided software, it is possible
to view and record the adjusted measurement values.
There are two methods of adjustment: adjusting by one point or adjusting by two
points. Adjustment for differences will be based upon the following simple equation
Y=aX+b.
X equals the measured value and Y equals the value after adjustment.

Connecting the Sensors

Connect the Sensor

*To avoid poor connections, be sure to push the sensor connector securely into the jack.

NOTE:

If a sensor extension cable is being used with the data logger connected by USB to your computer,
electromagnetic waves may cause large errors in measurements.

Handling the temperature/humidity sensor

- The temperature/humidity sensor should probably be changed after a period of about
one year.
After removing the sensor from its package, please change the temperature/humidity
sensor after one yearȧs usage.
During use, the temperature/humidity sensor will accumulate impurities (dirt) on the
surface of the sensor causing the sensor's accuracy and sensitivity to decrease.
If the sensor is being used in a bad environment (smoky or dusty places) it may be
necessary to change the sensor sooner.

- When the temperature/humidity sensor is not being used, please place it in the
attached vinyl bag with the drying agent included and store it in a cool dark place with
a temperature of between 5 to 25Ɏ and a humidity of below 30%RH.

- Attached to the temperature/humidity sensor are two stickers: a wetness detection
sticker and a temperature detection sticker.
If either of the stickers shows abnormality, you should change the old sensor to a new
one immediately.
