1 WHAT YOU CAN DO WITH DATALOGGER (FEATURES)

Datalogger is a device that logs data of temperature and/or humidity and
stores this data in its memory so that you can manage or analysis it on a
computer.

• Storage of up to 8100 lines of data. ( → P.43)
Ensuring long-term measurement:
If the Datalogger is set to log data every 30 minutes, approximately 165
days.
If the Datalogger is set to log data every 90 minutes, approximately 480
days.

• Four logging options to allow for selection of the setting
that best suits your needs ( → P.43)

1. Once (default)

The Datalogger keeps logging until the memory becomes full or 8100
lines of data are collected.

2. Repeatedly (overwriting)

The Datalogger overwrites the existing data from the start once the 8100
lines of data are collected. This setting is ideal for collecting data during
a certain period.

3. Ends at… (limited amount)
The Datalogger only collects a certain amount of data (up to 8100 lines)
as specified by the user. This setting is ideal when you want to limit the
amount of data to be collected.

4. By pages (partitioning)

The Datalogger performs four different logging tasks in sequence by
storing each task's data in the four divided memory blocks. This setting is
ideal if you want to collect data from multiple sites with one Datalogger.

• Scheduled logging ( → P.51)
You can preset the time to start logging. This setting is ideal if you want to
start logging automatically.

• Real-time communications ( → P.54)
The logged data of temperature and/or humidity can be downloaded to
computers while the Datalogger is still logging.

• USB connection

USB easily offers a connectivity to your computers than the conventional RS-232C.

1 |

• Displays the approximate amount of memory currently used. ( → P.44)
Easy to determine how much more logging is possible.

• Probes can be interchangeablely used.
The sensors are fully compatible among the series models so that, in case
of probe failure, it is easy to replace by interchanging with another probe.

• 14 logging intervals ( → P.42)
The logging intervals available are in seconds (1, 2, 5, 10, 15, 30) and in
minutes (1, 2, 5, 10, 15, 30, 60, 90).

• ID on each Datalogger ( → P.40)
The ID numbers of 1 to 9 can be set for easy identification when multiple
Dataloggers are used.

• No data loss even if the batteries go dead

There is no data loss even if there is a power failure, as the logged data is
stored in the EEPROM.

• Warning display for upper/lower limit of temperature or humidity

The Alarm mark lights on the LCD if the temperature or humidity exceeds
the preset threshold. This helps to prevent damage to your product.

• Easy to use software program for data analysis

The logged data can be fully utilized by plotting in graphs and displaying
in real time. Data can also be saved in CSV format and analyzed by
commercial spreadsheet software.

3. SYSTEM REQUIREMENTS

To use the Datalogger for Windows, your computer must meet the following
requirements.

• OS: Windows 2000 (SP 4 or later), Windows XP

• CPU: Pentium III 700 MHz or higher

• RAM: Minimum 256MB

• Hard disk drive: 150MB or more free space

• USB interface

5. GETTING STARTED

5-1. Installing Probe and Batteries

(1) Loosen the screw on the battery lid on the back of the main unit by rotating it counterclockwise with a coin

or the like.

TIP: The screw has been designed to be undetachable from the unit to prevent loosing it.

(2) Remove the battery cover.

(3) Load two AAA/R6 batteries. Be sure to place them in the correct directions.

(4) Install the battery cover.

(5) Install the temperature/temperature and

humidity probe as follows:
Push the sensor unit into the sensor connector
until you hear a “click”.
To remove the sensor, pull it straight toward

you in the reverse direction of the
installation. Never rotate the
sensor unit while pulling.

5-2. Setting Current Date and Time

(1) Press the POWER ON/OFF key for one second or more to turn the unit on. The LCD turns on to indicate that

the SK-L200T II or SK-L200TH IIα is in the measurement state for temperature or temperature and humidity,
respectively.

(2) Press the MODE key twice.
(3) The TIME mark lights and the "year" display flashes. Use the ▲ or ▼ key to set the year (ex. “2006”)
TIPS:

• Hold down the ▲ / ▼ key to quickly change the value.

• Press the MODE key to skip the current setting and to proceed to

• the next item.

• If no key is pressed for one minute, the unit returns to the measurement state.

(4) Press the REC/STOP key to confirm the year setting.

(5) The "month" display flashes. Use the ▲ or ▼ key to set the month (ex. “3” for March)

(6) Press the REC/STOP key to confirm the month setting.

(7) The "date" display flashes. Use the ▲ or ▼ key to set to "1". (For the day)

(8) Press the REC/STOP key to confirm the date setting.

(9) The "hour" display flashes. Use the ▲ or ▼ key to set to "10". (For the hour)

(10) Press the REC/STOP key to confirm the hour setting.

7 |

NOTE: The Datalogger uses the 24-hour clock format.

(11) The "minute" display flashes. Use the ▲ or ▼ key to set to "30". (For the minutes)

(12) Press the REC/STOP key to confirm the minute setting. The Datalogger starts clocking from the "00"

seconds.

(13) Press the CALL/OUT key once. Now the setting of current date and time is complete. The SK-L200T II

or SK-L200TH IIα returns to the measurement state for temperature or temperature and humidity,

respectively.

(14) Press and hold the POWER ON/OFF key for one second or more to turn off the unit.

!! Caution !!

6. CAUTION ON USE

• Be sure to observe the operating temperature range of your Datalogger. Although the SK-L200T II

Datalogger can be used for measuring low temperatures or high temperatures with the probe with sensor
cord, never bring the unit to the ultra-low temperature or ultra-high temperature atmosphere or place it in
such an environment. Doing so will damage the electronic circuit inside. The operating temperature range of
the Datalogger is -10 to 60°C. For further information, please see "Specifications" on page 64.

• When the Datalogger is used at the temperature 5°C or below Always turn off the Datalogger at the ambient

temperature if it was used at 5°C or lower. Moving the Datalogger to a warmer place (room temperature) to
turn it off may form condensation inside and outside of the unit. Condensation can cause an unstable
electronic circuit, resulting in a malfunction.

NOTE: It is not necessary to observe the above caution when the Datalogger stops operation due to a memory

full state, as it automatically turns off. However, be sure that the unit surface is dry and no water drops
are present before turning it on again.

• Never wet the Datalogger, as it is not waterproof.

• The air vent on the sensor is designed to improve the response speed. Do not cover the vent with vinyl tape

or the like. Protect the vent from water splash.

• When the unit is hung on the wall, make sure that it is securely fastened.

•
