Introduction
Thank you for purchasing the SK-L200II Series Dataloggers.
・
This product is designed to measure temperature or temperature/humidity.
Do not use it for other purposes.
・
Read this manual thoroughly before using. Keep the manual in a safe place
for future reference whenever necessary.
WARNING
The SK-L200II Series Dataloggers are not explosion-proof. Never use it in
an atmosphere containing ammable gases.
Beware of explosion!

Safety Precautions
To use the Datalogger safely, follow the precautions below.
・
Never disassemble or modify the unit. Doing so may cause a malfunction.
・
The unit is precision-machined. Never drop the unit or knock it over.
・
Do not use the unit in a place exposed to direct sunlight or near a heat
source. Doing so affects the measurement accuracy, and could result in a
deformation or malfunction of the unit.
・
If this unit is used in an environment where electrical noise is generated,
the display may become unstable or the measurement error may
increase.
・
Never use the unit in an environment other than standard atmosphere (air
composition).
・
The main unit and probes are not waterproof. Never let them get wet.
・
Measuring temperature or humidity outside the measurable range may
result in unit and/or sensor malfunctions.
・
If the unit is not to be used for a long period of time, remove the batteries.
Otherwise, the batteries may leak, resulting in malfunctions.
・
Do not dispose of used batteries in a re.
・
Keep the battery out of the reach of children. If the battery has been
swallowed accidentally, consult a doctor immediately.
・
For environmental conservation purposes, dispose of the used battery in
compliance with local rules and regulations.

−3−
・
Do not modify, forcibly pull, bend or tie the sensor cord. Placing heavy
objects on the sensor cord or heating it will also damage the cord.
・
Do not wash or wipe this unit with alcohol, thinner, or other organic
solvents. If the unit becomes dirty, wipe it with a tightly-wrung gauze or
the like that has been dipped in warm water with neutral detergent.
・
Never touch the humidity sensor (Model SK-L200TH IIα) with bare hands.
・
If the dew point is exceeded and condensation occurs while the humidity
sensor (SK-LTH IIα series) is being used, immediately stop using and
allow time for the sensor to dry naturally at room temperature.
・
The SK-LTH IIα series probes are used with SK-L200TH IIα and are not
usable with SK-L200TH II.
For repair or calibration, contact the retailer from which the Datalogger was
purchased or your nearest local sales representative.

Overview
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.
Features
●Storage of up to 8100 lines of data. ( →P.49)
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.51)
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.

−5−
3. Ends at… (limited amount)
The Datalogger only collects a certain amount of data (up to 8100 lines)
as specied 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.60)
You can preset the time to start logging. This setting is ideal if you want to
start logging automatically.
 ●Real-time communications ( →P.64)
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.

−6−
 ●Displays the approximate amount of memory currently used.
(→P.52)
Easy to determine how much more logging is possible.
 ●Probes can be interchangeablely used.
The probes 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.50)
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.48)
The ID numbers of 1 to 9 can be set for easy identication 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.

−7−
 ●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.
